Roman Roads History Map
They say all roads lead to Rome, and the Roman Empire did indeed have an impressive network of roads that stretched across Europe, the Middle East, and North Africa. Wikimedia Commons
Roman Coins Found In Britain
For another way to imagine Rome's reach, consider this history map. Every dot marks a place where Roman coins have been found in Britain. Portable Antiquities Scheme/Flickr
Expansion Of The Mongol Empire
The Roman Empire may have been grand for its time — but it was nothing compared to that of the Mongols.
At its height, the Mongol Empire controlled a whopping 12 million square miles, making it the largest contiguous empire in world history.
Initially founded by Genghis Khan, the empire began in 1206 thanks to Khan's ability to unite nomadic tribes and to conquer large swaths of land across Asia. Wikimedia Commons
Height Of The Ottoman Empire
The Ottoman Empire, too, once stretched far and wide. Here is the expanse of its territory in 1683, when the empire sprawled across 2 million square miles. Wikimedia Commons
Viking Expansion History Map
Though not as expansive as the Romans or the Mongols, the Vikings certainly left their mark on history. This map shows how their settlements spread, and which areas of Europe were most vulnerable to their attacks. Wikimedia Commons
Countries That Were Never Invaded By The British
"The sun never sets on the British Empire."
Indeed, the British Empire once spanned almost the entirety of the planet. From the Age of Exploration to its waning days in the mid-20th century, nearly 98 percent of Earth's present-day population lives in a country that was once colonized or subjugated by the British.
Just 22 countries in the world have never been invaded by the British — and they're shown in purple on this map. Author Stuart Laycock
European Colonization History Map
Likewise, much of the world has been colonized by Europe. Only a few countries (shown in light orange and yellow) escaped direct control by Europe. Max Fisher/Vox
Division Of Colonial Africa
This 1908 map shows how Europe carved up Africa through colonization.
Though some of these boundaries still hold true today, many European colonizers divided Africa with little regard for its diverse tribes, cultures, and languages. Stark divisions within countries continue to contribute to unrest and violence to this day. Library of Congress
Spread Of Christianity In Europe
Christianity started out small, but rapidly spread across Europe. Though early Christians were persecuted by the Roman Empire, Rome eventually became an important holy city to Christians — especially Catholics — as the home of the Vatican. oglach/Reddit
Spread Of Religions From The Middle East
Christianity was far from the only religion to find believers across the world. Like Judaism and Mithraism — a religion based on astrology that existed between the 1st and 4th centuries A.D. — Christianity emerged in the Middle East and rapidly spread.The Concise Atlas of World History
Spread Of Islam In The Middle East
This world history map shows the spread of Islam. Introduced by the Prophet Muhammad in the 7th century, Islam spread rapidly across the Middle East and remains the region's primary religion to this day. Wikimedia Commons
Napoleonic Empire History Map
At the onset of the 19th century, Napoleon Bonaparte marched across much of Europe. This map shows the peak of Napoleon's empire, which began to decline after his failed Russian campaign of 1812. Wikimedia Commons
The German Reich (1871-1918)
This map shows the sprawl of the German Reich during the late 19th and early 20th centuries. Once German states unified in 1871, they formed a massive state, which threatened the balance of power in Europe. Wikimedia Commons
Europe After World War I
After World War I, Germany's borders were greatly reduced. All of Europe looked different following the conflict. Wikimedia Commons
Europe Under Nazi Control During World War II
At the height of the Nazi regime, the Third Reich controlled most of the European continent. From areas under direct occupation to German puppet states, Nazi rule stretched from France to the Balkans to western Russia.
Though they were slowly turned back by the Red Army, Adolf Hitler refused to accept defeat until 1945 — ensuring that much of Germany would be reduced to rubble by the end of World War II.Wikimedia Commons
Changing Power Dynamics During World War II
But World War II was truly a world war. In this animated world history map of Europe, Asia, and Africa, you can see how alliances dramatically shifted during the victories and losses of the war. EmperorTigerstar/YouTube
Map Of The D-Day Attack
On June 6, 1944, the Allied powers launched an aggressive attack by storming the beaches of Normandy. This map shows the extent of their assault. More than 4,000 Allied troops died, but British, American, and Canadian forces were able to breach the Nazis' defenses. This helped turn the tide against Germany during the war.Wikimedia Commons
World War II After D-Day
This remarkable map, which depicts the days following D-Day, shows how the balance of power swiftly shifted. EmperorTigerstar/YouTube
Bombing Of Japanese Cities
This map shows, in red, how much of major Japanese cities were destroyed by bombing during World War II.
In addition to nuclear bombs, Japan was also devastated by fire bombings. Wikimedia Commons
Bombings In London During World War II
Likewise, this map shows every place in London that was bombed during the Blitz, which took place between October 7, 1940, and June 6, 1941. More than 40,000 British civilians were killed in these attacks during World War II. Bomb Sight project
Bombing Of Dresden
Dresden, Germany, was also extensively bombed during World War II. The purple areas on the map show areas destroyed or badly damaged by these attacks. Imperial War Museum
Jewish Population In Europe Before And After The Holocaust
The Holocaust decimated Europe's Jewish population, killing some six million Jews by the end of World War II. The devastating impact of the Holocaust can still be seen in Europe today, where the Jewish population has remained relatively small compared to 1933. Jewish Data Bank
The Spread Of The United Nations
Out of the horror of World War II, however, came the hopeful idea for the United Nations.
This map shows how membership slowly but steadily spread over much of the globe. Of the 195 countries recognized by the United States, 193 are U.N. members.Wikimedia Commons
Native American Tribal Lands Before Colonization
This map shows the great swaths of land held by different Native American tribes before European settlers arrived in North America. Library of Congress
Indigenous Languages In The Americas Before Colonization
Similarly, this map shows the division of languages among various Indigenous American tribes. Wikimedia Commons
Extermination Of The American Bison
This startling map shows how herds of the American bison were steadily and systematically slaughtered, especially during the late 19th century.
After the Civil War, Americans increasingly pushed west into land held by Indigenous people. To eradicate these tribes — or at least force them to submit to American authorities — the U.S. government decided to wipe out their primary source of food: bison.
They put Civil War hero William T. Sherman in charge of the endeavor, who said, "I think it would be wise to invite all the sportsmen of England and America…this fall for a Grand Buffalo hunt and make one grand sweep of them all."Wikimedia Commons
Slave States And Free States Before The Civil War
This map shows the teetering balance between "slave states" and "free states" leading up to the Civil War. Though American policymakers tried to avoid conflict with various compromises, the tension over slavery in the United States eventually boiled over into war. Wikimedia Commons
Lynchings In The United States
This powerful map shows the recorded lynchings across the United States from 1900 to 1931, represented with dots. Though most were concentrated in the South, lynchings happened all over the country. Library of Congress
Every Presidential Election From 1860 To 2004
Ever since the Civil War, Americans have swung between supporting Democrats and Republicans for president.
Though the South used to favor Democratic candidates, and the North used to favor Republican ones, shifting demographics and party priorities eventually switched regional preferences in many areas. Wikimedia Commons
Changing Immigration Trends In The United States
This animated map shows how immigration trends changed in the United States, from primarily German immigrants to primarily Mexican ones. Pew Research Center
Diversity In The United States
This map helps paint a picture of American diversity. It highlights which ethnicities have made a home in certain counties in the greatest numbers — and where these communities were living by the year 2000. U.S. Census Bureau
Evolution Of The United States
The United States famously started as 13 colonies before solidifying into states and expanding into territories. This map shows the evolution of the United States — and how it became the country we know today. Wikimedia Commons
