Map the Roman Empire

Build a source-backed interactive map explaining how Rome governed its empire.

Introduction

30 Second Summary

A long list of emperors and dates can make the Roman Empire feel like a timeline instead of a place. Geography reveals how power reached cities and frontiers thousands of miles apart.

In this project, you will build an interactive map in Google My Maps that uses five places to explain how Rome governed a large and diverse empire. You will turn source-backed evidence into a geographic argument about political centers, provincial life, and frontier control.

What You'll Build

Picture your final map open in Safari with five evidence cards grouped into color-coded layers that reveal how Rome held distant regions together.

By the end of this project, you'll have:

A shareable interactive map where viewers move between Rome, Pompeii, Hadrian's Wall, Timgad, and Constantinople to open five source-backed evidence cards.
Three color-coded analytical layers that viewers can toggle to compare imperial centers, provincial life, and frontier control.
A concise historical conclusion answering How did Rome govern such a large and diverse empire?.
Secret Mission: Add Palmyra to show how Roman rule could coexist with local traditions and Persian influences.

Are there any prerequisites?

You need a Mac with internet access, a Google Account, and basic familiarity with the Roman Empire. Google My Maps runs in your current browser, so this project needs no installation or additional spend.

Before We Start

Before the mapping begins, lock in the historical question that guides every place you add. You are building an evidence-based interactive map that uses geography to explain how imperial centers, provincial life, and frontier control helped Rome govern a large and diverse empire.

Set Up the Map

The historical question you chose needs a clear geographic home. A working map keeps each later location tied to that question.

Google My Maps lets you organize evidence around place. Starting with the question prevents the project from becoming an unfocused tour of ruins.

In this step, get ready to:

Open Google My Maps in Safari with your Google Account.
Create the titled map with its guiding question.
Center the empty map on Rome without adding a marker.

Open Google My Maps in Safari

Google My Maps stores your map with your Google Account. This keeps your work available when you return later.

Press Command-Space bar to open Spotlight.

You’ll see the Spotlight search field on your Mac.

Type Safari into the Spotlight search field.
Select Safari from the search results.

Safari opens with a browser window ready for the My Maps address.

Enter mymaps.google.com in Safari’s address bar.
Press Return to load Google My Maps.

This sign-in uses your existing Google Account. Your password stays inside Google’s sign-in page.

Click Sign in when Google requests authentication.
Complete authentication with your confirmed Google Account.

That first gate is cleared. Your account now has an open Google My Maps editor ready for the project.

Editor not loading?

Reload mymaps.google.com if the editor area remains blank.
Complete any Google Account prompt still open in another Safari tab.

Ask for help with the sign-in or loading problem.

Name your new map

A precise title signals that this map explains how Roman power worked. Every evidence card you add later contributes to that explanation.

Click Create a new map.

You’ll see a new map editor. One empty layer is ready for future locations.

Click Untitled map in the top-left map panel.

The map details dialog opens with space for a name and description.

Enter How Rome Held an Empire Together as the map’s name.
Click Save.

Good start. The editor now displays How Rome Held an Empire Together above its empty layer.

Add the question and locate Rome

The description gives your spatial history project a test for choosing evidence. Rome then provides the first geographic reference point for the empire’s story.

Click How Rome Held an Empire Together in the top-left map panel.

The map details dialog reopens so you can add the historical question.

Paste Question: How did Rome govern such a large and diverse empire? Evidence will be organized as imperial centers, provincial life, and frontier control. into the description area.
Click Save.

The guiding question now appears beneath the map title. The initial layer remains empty.

Before you search, do you expect the map title to remain visible when the view moves to Rome?

Type Rome into the map’s search bar.
Press Return to run the search.

You’ll see the map move to Rome while the project title remains visible.

Confirm the search result points to the city in central Italy.
Leave Add to map untouched.
Confirm the initial layer still contains no markers.

Your map now has a clear title and a source question. Rome is centered as the starting point without becoming a marker yet.

Your map has its purpose and starting position. Next up, you’ll turn Rome and Pompeii into the first source-backed evidence stops.

Build the First Two Evidence Stops

Your Google My Maps project now has a focused historical question. The open map in Safari is ready for evidence that begins answering it.

A pin shows where something happened. Source-backed evidence cards reveal the contrast between imperial power in Rome and social life in Pompeii.

In this step, get ready to:

Add a Rome marker with evidence about imperial authority.
Add a Pompeii marker with evidence about urban life.
Verify that both markers open complete evidence cards.

Add Rome as an imperial center

Rome provides the political side of your first comparison. Its card connects the start of the Roman Empire to the continued use of republican institutions.

In the Rome search result that is already open, confirm the pin points to the city of Rome in Italy.
Click Add to map in the result card.
Select the edit icon in the Rome marker's card.
Paste the following evidence card into the description box:

Date: 27 B.C. Evidence: The Senate awarded Octavian the title Augustus, beginning the Roman Empire, while republican forms continued alongside expanding imperial control. What it shows: Rome concentrated authority while preserving older political language and institutions. Source: https://www.metmuseum.org/essays/the-roman-empire-27-b-c-393-a-d

What Does This Evidence Card Do?

The Date field anchors the evidence in 27 B.C..
The Evidence field states the source-backed historical claim.
The What it shows field interprets how Rome concentrated authority.
The Source field lets a viewer trace the claim to The Metropolitan Museum of Art.

Click the card's save control.
Click the Rome marker on the map.

Your Rome card opens with a date, an evidence statement, an interpretation, and a source link. That is your first source-backed stop complete.

Is the Rome Card Missing?

Confirm that you selected the search result for the city of Rome before clicking Add to map.
Reopen the Rome card's edit control if the description did not save.
Compare the saved card with the evidence text above if a field or source link is missing.

Help me fix my Rome marker or evidence card in Google My Maps.

Add Pompeii as a window into urban life

Pompeii shifts the map from imperial government to daily life. Its surviving houses show how status shaped the spaces where Roman people lived and worked.

Enter Pompeii in the map's search bar.
Select the result that points to Pompeii in Italy.
Click Add to map in the result card.
Select the edit icon in the Pompeii marker's card.
Paste the following evidence card into the description box:

Focus: Roman urban life and social hierarchy. Evidence: Much of Pompeii consisted of private households. Elite domus centered on an atrium and could include bedrooms, dining rooms, servants' quarters, a tablinum, and a peristyle, while middle- and lower-class homes were smaller and simpler. What it shows: Roman urban culture connected household design, status, work, and public identity. Source: https://pompeiisites.org/en/pompeii-map/analysis/roman-housing/

What Does This Evidence Card Do?

The Focus field names urban life and social hierarchy as the card's theme.
The Evidence field uses household layouts to support its historical claim.
The What it shows field links domestic spaces to status and public identity.
The Source field connects the card to the Archaeological Park of Pompeii.

Click the card's save control.
Click the Pompeii marker on the map.

Your Pompeii card opens with a focus, an evidence statement, an interpretation, and a source link. You now have evidence for both political authority and urban society.

Is Pompeii in the Wrong Place?

Confirm that the selected result points to Pompeii in Italy.
Search for Pompeii again if the marker appears in another region.
Reopen the Pompeii card's edit control if its evidence text is incomplete.

Help me correct my Pompeii marker or evidence card in Google My Maps.

Verify the first historical contrast

Before you check the finished pair, predict which details will make Rome feel like a political center while Pompeii feels like a lived city.

Click the Rome marker.

You'll see a card containing the 27 B.C. date, a claim about Augustus, an interpretation about concentrated authority, and a source link.

Click the Pompeii marker.

You'll see a card containing its urban-life focus, evidence about private households, an interpretation about social identity, and a source link.

Check the initial unnamed layer in the left panel.

You'll see both Rome and Pompeii listed in the layer. Your map now presents an immediate contrast between imperial power and life inside an Italian city.

Your first two places already tell different parts of Rome's story. Next, you'll extend that story across Britain, North Africa, and the eastern Mediterranean.

Map the Empire's Reach

Rome and Pompeii now anchor your Google My Maps project in Italy. The next three places extend its story to Britain, North Africa, and the eastern Mediterranean.

This wider view introduces spatial history as a way to examine imperial scale. By the end, you will decide whether five uniform pins reveal the relationships among centers, provinces, and frontiers.

In this step, get ready to:

Add Hadrian's Wall as evidence of frontier management.
Add Timgad as evidence of provincial planning.
Add Constantinople as evidence of political adaptation.

Add Hadrian's Wall as a frontier

Hadrian's Wall adds frontier control to your geographic evidence. Its military infrastructure shows how Rome managed movement at the edge of the empire.

Return to the search bar at the top of the Google My Maps editor from earlier.
Enter Hadrian's Wall.
Select the result located in northern England.
Click Add to map in the result card.

You'll see a new Hadrian's Wall marker on the map. Its name also appears in the initial unnamed layer.

Click the Hadrian's Wall marker in the initial unnamed layer.
Click the pencil-shaped editing control in its card.
Replace the card description by pasting the text below:

Date: AD 122. Evidence: The Roman army built the wall on Hadrian's orders as the north-west frontier, supported by gates, towers, forts, and auxiliary troops. What it shows: Borders were managed through infrastructure, surveillance, mobility, and permanent military communities. Source: https://www.english-heritage.org.uk/visit/places/hadrians-wall/hadrians-wall-history-and-stories/history

What Does This Evidence Card Show?

The date AD 122 anchors the wall in Hadrian's reign.
The evidence connects the wall to gates, towers, forts, and auxiliary troops.
The interpretation presents the frontier as a managed system of infrastructure and surveillance.
The source gives viewers an authoritative place to check the claim.

Click Save in the card editor.
Click the Hadrian's Wall marker on the map.

You'll see a card containing the date, historical evidence, interpretation, and English Heritage source link. Your map now reaches Rome's north-west frontier through evidence of military infrastructure.

Can't Find the Correct Wall?

Confirm that the selected search result lies in northern England before clicking Add to map.
Reopen the pencil-shaped editing control if the evidence card did not retain the full text.

Help me correct my Hadrian's Wall marker and evidence card in Google My Maps.

Add Timgad as a planned provincial city

Timgad shows how Rome projected authority through planned urbanism far from Italy. Its square enclosure and orthogonal street plan make that provincial strategy visible.

Return to the search bar in the map editor.
Enter Timgad, Algeria.
Select the archaeological-site result in Algeria.
Click Add to map in the result card.

You'll see the Timgad, Algeria marker appear in North Africa. Its name remains in the same initial unnamed layer as the first three places.

Click the Timgad, Algeria marker in the initial unnamed layer.
Click the pencil-shaped editing control in its card.
Replace the card description by pasting the text below:

Date: AD 100. Evidence: Trajan founded Timgad as a military colony with a square enclosure and an orthogonal plan based on the cardo and decumanus. What it shows: Rome projected authority through planned cities and recognizable civic forms far from Italy. Source: https://whc.unesco.org/en/list/194/

What Does This Evidence Card Show?

The date AD 100 places Timgad's foundation during Trajan's reign.
The evidence identifies its military origin and orthogonal plan.
The interpretation connects urban planning with Roman authority far from Italy.
The UNESCO source supports the marker's historical claim.

Click Save in the card editor.
Click the Timgad, Algeria marker on the map.

You'll see a card containing AD 100, the evidence about Timgad's plan, an interpretation of provincial authority, and the UNESCO source link. You have added a provincial city that makes Roman planning visible in North Africa.

Is Timgad Missing or Misplaced?

Repeat the search with the full value Timgad, Algeria if the result appears outside Algeria.
Reopen the marker card if its description does not include the UNESCO source link.

Help me fix the location or evidence card for Timgad in Google My Maps.

Add Constantinople as a later capital

Constantinople adds continuity and change to the map. Searching for its modern location lets you place the late Roman capital accurately before giving the marker its historical name.

Return to the search bar in the map editor.
Enter Istanbul.
Select the city result for Istanbul.
Click Add to map in the result card.

You'll see an Istanbul marker at the eastern end of your growing map. The marker initially uses the modern city name.

Click the Istanbul marker in the initial unnamed layer.
Click the pencil-shaped editing control in its card.
Replace Istanbul in the marker name field with Constantinople.
Replace the card description by pasting the text below:

Date: 330 A.D. Evidence: Constantine founded a new capital at Byzantium and renamed it Constantinople after reuniting the empire. What it shows: Roman government adapted by shifting its political center eastward. Source: https://www.metmuseum.org/essays/the-roman-empire-27-b-c-393-a-d

What Does This Evidence Card Show?

The date 330 A.D. identifies the foundation of the new capital.
The evidence connects Constantinople with Constantine's reunification of the empire.
The interpretation shows Roman government adapting through an eastward shift in political power.
The Met source supports the card's historical account.

Click Save in the card editor.
Click the Constantinople marker on the map.

You'll see the historical name Constantinople above a card containing the date, evidence, interpretation, and Met source link. Your map now connects Rome with a later political center in the east.

Still Seeing Istanbul?

Reopen the marker's pencil-shaped editing control if its displayed name still says Istanbul.
Enter Constantinople in the marker name field before clicking Save.

Help me rename my Istanbul marker to Constantinople without changing its location.

Before you zoom out, do you think five pins in one uniform layer will show which places were imperial centers, provincial cities, or a frontier?

Use the minus zoom control until Britain, North Africa, Italy, and Istanbul fit in the map view.
Count all five visible markers.
Compare the markers' organization against the three categories in the map description.

You'll see Rome, Pompeii, Hadrian's Wall, Timgad, and Constantinople spread across the map. Their identical organization keeps imperial centers, provincial cities, and frontier control visually indistinct.

Why Does the Map Feel Flat?

The five places prove that the Roman Empire covered a vast area. Their shared layer gives every marker the same visual role.

The map shows where the evidence belongs without showing how the places relate. That limitation is the intended result of this test.

Your five-place map now makes the empire's reach visible. Next, you will reorganize those markers so their historical roles become visible too.

Organize the Historical Argument

Your source-backed map now stretches from Britain to North Africa. It also reaches from Italy to Istanbul.

The single-layer view flattened every place into one visual category. Analytical layers in Google My Maps reveal the relationships among those places.

In this step, get ready to:

Create three named analytical layers.
Sort every marker into its matching category.
Style each category with one uniform color.

Create the analytical layers

A layer groups related markers into one visual category. Its checkbox controls that category as a unit.

The layer names are modern analytical labels created for this project.

Click the layer title above Rome in the left panel.
Enter Imperial Centers in the layer name field.
Select the dialog's confirmation control.
Click Add layer in the left panel.
Click the new layer's title.
Enter Provincial Cities and Daily Life in the layer name field.
Select the dialog's confirmation control.

The left panel now shows categories for imperial centers plus provincial life.

Click Add layer again.
Click the newest layer's title.
Enter Frontier Control in the layer name field.
Select the dialog's confirmation control.

This is the key structural win: your map now has three historical categories.

Sort the five markers

The next move separates provincial evidence from the political centers. It also isolates the frontier evidence.

Confirm Rome appears under Imperial Centers.
Confirm Constantinople appears under Imperial Centers.
Drag Pompeii into Provincial Cities and Daily Life.
Drag Timgad into Provincial Cities and Daily Life.

The provincial category now contains Pompeii plus Timgad.

Drag Hadrian's Wall into Frontier Control.

The frontier category now contains Hadrian's Wall alone.

Why do these categories matter?

Spatial history uses location to test historical claims. These layers turn five separate case studies into a comparison.

The Imperial Centers layer connects Rome with Constantinople to show that political authority could shift eastward.
The Provincial Cities and Daily Life layer connects household life at Pompeii with planned urbanism at Timgad.
The Frontier Control layer isolates the military infrastructure that managed Rome's north-west border.

Color-code the category layers

A Uniform style gives every marker in a layer the same visual signal. A distinct color makes each category readable through the legend.

Click Style under Imperial Centers.
Select Uniform style.

The style controls now apply one appearance across both center markers.

Click Color.
Select a blue swatch.

Rome plus Constantinople now use blue markers.

Click Style under Provincial Cities and Daily Life.
Select Uniform style.

The provincial markers now share one style setting.

Click Color.
Select a green swatch.

Pompeii plus Timgad now use green markers.

Click Style under Frontier Control.
Select Uniform style.

The frontier marker now has a category-wide style setting.

Click Color.
Select a red swatch.

Hadrian's Wall now uses a red marker.

Pause for one prediction: decide which markers should disappear when you clear each layer's checkbox.
Clear the checkbox beside Imperial Centers.
Select the checkbox beside Imperial Centers.
Clear the checkbox beside Provincial Cities and Daily Life.
Select the checkbox beside Provincial Cities and Daily Life.
Clear the checkbox beside Frontier Control.
Select the checkbox beside Frontier Control.

What should I see?

Toggling Imperial Centers hides and restores Rome plus Constantinople.

Toggling Provincial Cities and Daily Life hides and restores Pompeii plus Timgad.

Toggling Frontier Control hides and restores Hadrian's Wall.

Your markers now form a readable historical argument. The layer controls reveal each category on demand.

Layers not behaving as expected?

Drag a misplaced marker into its correct layer if it disappears with the wrong category.
Select Uniform style again for any layer whose markers do not match.
Choose the assigned color again after the style is uniform.

Help me fix the marker categories or colors in my Google My Maps project.

Your map now distinguishes political centers from provincial life. Next, you will write the conclusion that connects those categories into one interpretation.

Preview and Share Your Interpretation

Your five markers now sit in three color-coded categories. Next, you will turn that structure into a conclusion another person can follow.

A historical map becomes persuasive when its evidence supports a clear claim. You will test the finished viewer in Google My Maps before sharing the link through Safari.

In this step, get ready to:

Write a three-part conclusion supported by the mapped evidence.
Inspect every layer and evidence card in Preview.
Enable link sharing for one trusted viewer.

Add the three-part conclusion

A conclusion connects the five places to one answer about Roman government. Its final sentence also preserves regional diversity within that explanation.

Select the map title How Rome Held an Empire Together in the left panel.
Click the map description field below the title.
Place your cursor after the final full stop in the existing description.
Press the Space key once.
Add the three-part conclusion by pasting this text:

Rome governed through centralized authority concentrated in imperial centers such as Rome and later Constantinople. Planned cities such as Timgad and frontier infrastructure such as Hadrian's Wall show how civic forms, military communities, surveillance, and mobility extended that authority across distance. Rome integrated regions into imperial systems without making every region identical.

How Does the Conclusion Work?

The first sentence connects centralized authority to Rome. It also recognizes the later political importance of Constantinople.
The second sentence uses Timgad as evidence for planned provincial cities. It uses Hadrian's Wall as evidence for frontier infrastructure.
The final sentence limits the argument. Imperial integration still allowed regional differences.

Click Save.
Select the map title in the left panel.
Confirm the description ends with the three sentences shown above.

Is the Conclusion Missing or Joined Together?

Check that you pasted the conclusion inside the map description field.
Add one space between the original description and the first new sentence.
Click Save again after correcting the text.

Get help checking the map description.

You have completed the historian's hardest task. The five locations now support one concise claim about Roman imperial power.

Test the viewer experience

Preview shows the map from a viewer's perspective. This check reveals whether the categories remain clear without the editor controls.

Before you enter Preview, consider whether each layer will tell a distinct part of the argument.

Click Preview in the map editor.
Click the checkbox beside Imperial Centers to hide its blue markers.
Click the same checkbox again to restore its blue markers.
Click the checkbox beside Provincial Cities and Daily Life to hide its green markers.
Click the same checkbox again to restore its green markers.
Click the checkbox beside Frontier Control to hide its red marker.
Click the same checkbox again to restore its red marker.

The matching markers should disappear when you hide each layer. They should return in their category color when you restore it.

What Does This Check Prove?

Each layer isolates one part of your argument. The viewer can compare political centers, provincial life, and frontier control without losing the empire-wide picture.

Confirm the title How Rome Held an Empire Together remains visible.
Confirm the complete three-part conclusion remains visible.
Open all five markers one at a time.
Check each evidence card for its claim.
Check each evidence card for its interpretation.
Check each evidence card for its source link.
Return to the editor if you find a missing source or misplaced marker.
Correct the missing source or misplaced marker.

Select Preview again after any correction.
Repeat the affected layer or evidence-card check.

You should see all three layer names with their category colors. Each of the five markers should open a card containing evidence, an interpretation, and a source link.

Is Something Missing in Preview?

Return to the editor to check that all three layer checkboxes are selected.
Check that the missing marker remains inside its intended layer.
Open the affected marker in the editor to restore any missing source text.

Help me diagnose a missing Preview item.

Your viewer check is complete. The map now presents the same argument in both the editor and Preview.

Share the finished map

Link sharing lets another person test the map as a viewer. A share URL can be forwarded, so send it to one trusted person for this check.

Return to the map editor from Preview.
Click Share.
Enable Allow link sharing.
Follow the on-screen instructions to copy or send the map URL to one trusted viewer.

Before your viewer opens the link, predict whether the map will communicate its three-part argument without your explanation.

Ask your trusted viewer to open the shared URL.
Ask your trusted viewer to toggle all three layers one at a time.
Ask your trusted viewer to open each of the five evidence cards.
Ask your trusted viewer to confirm that each card includes a source link.

Your viewer should see the title, the three layer names, the category colors, and the conclusion. Each marker should open its cited evidence card.

Can Your Viewer Not Open the Map?

Return to Share in the map editor.
Confirm that Allow link sharing remains enabled.
Copy the share URL again.
Send the new copy to your trusted viewer.

Help me troubleshoot the shared map link.

Your map is ready for an audience. A trusted viewer can now follow the evidence from imperial centers to provincial cities and frontier control.

Nice Work!

You did it! Your Google My Maps project now guides a viewer across six source-backed Roman locations. Its four analytical layers turn geography into a historical argument about power, daily life, frontiers, and local adaptation.

You've learned how to:

Built a shareable interactive map that connects Rome, Pompeii, Hadrian's Wall, Timgad, Constantinople, and Palmyra across Europe, North Africa, and western Asia.
Turned six locations into source-backed evidence cards that connect historical details to interpretations of government, urban life, frontier control, or local adaptation.
Used color-coded layers to transform uniform pins into a spatial history argument. Wrote a cited conclusion about centralized authority, infrastructure, adaptation, and regional diversity. Checked the viewer experience through Preview before sharing the map by link.
Secret Mission: Added Palmyra as a comparison with Timgad. Its evidence shows how Roman connection could support cultural synthesis without erasing local traditions or Persian influences.
