The Don River is the highlighted river, which runs through the southern part of European Russia.
Historically, it was known to the Greeks as the Tanais and was viewed by some ancient geographers as the boundary between Europe and Asia. It was also an important trade route connecting the Vikings, the Eastern Romans (Byzantine Empire), the Scythians, and the Middle East.
During World War II, the river also played a crucial role in the Battle of Stalingrad. Although Stalingrad was located on the Volga River, the Don flowed nearby. During Operation Uranus in November 1942, Soviet forces smashed through the weaker Axis-allied Romanian armies defending the flanks of the German 6th Army. The two Soviet pincers then met at Kalach-on-Don, encircling the German 6th Army and trapping it inside Stalingrad.
What is the name of the river highlighted on this map? If you can’t name it, can you identify the country it runs through?

Mexico has by far the larger population, with about 133 million people compared to South Africa’s roughly 65 million.
Yesterday’s match was just the second time the two countries had faced each other at a World Cup. Their first meeting ended in a 1–1 draw during the 2010 FIFA World Cup in Johannesburg, South Africa.
Mexico defeated South Africa 2–0 in the opening match of the 2026 FIFA World Cup. Which country has the larger population?

James K. Polk was president of the United States during the largest territorial expansion in the nation’s history. Polk is considered one of the most consequential one-term presidents.
He ran on the idea of Manifest Destiny, and he delivered on it by expanding the country by more than one million square miles. Polk oversaw the final stage of the annexation of Texas, which was admitted as a state in December 1845. He also resolved the Oregon boundary dispute in 1846 through a compromise that set the border at the 49th parallel, securing present-day Oregon, Washington, Idaho, and parts of Montana and Wyoming. Finally, the Mexican Cession, acquired at the conclusion of the Mexican-American War in 1848, brought vast territories that now make up much of the modern-day American Southwest.
Polk promised to serve only a single term. Just a few months after leaving office in March 1849, he died of cholera. When it comes to achieving major goals in a short period of time (including territorial expansion, resolving border disputes, lowering tariffs, and reestablishing an independent treasury) was Polk the most efficient president ever?

While traveling through Ohio yesterday, I came across this map of Ohio’s physiographic regions at a rest stop.
Included are the Lake Plains, Glaciated Appalachian Plateau, Unglaciated Appalachian Plateau, Till Plains, and a strip of Bluegrass in Ohio’s extreme southwest.
For some reason, I’m fascinated with maps like this!

The Yukon (highlighted) is the third-longest river in North America, behind the Missouri and Mississippi.
The river also played a crucial role in the Klondike Gold Rush of the late 1890s. Along with its tributary, the Klondike River, it served as the primary transportation artery. Along the Yukon River on the Canadian side, Dawson City rapidly grew from a tiny settlement to a boomtown of roughly 17,000–30,000 people.

Tyre is the answer. It is an ancient city founded by the Phoenicians and is one of the oldest continuously inhabited cities in the world.
It was known for trade and for its luxurious Tyrian purple dye (made from murex snails), and was also mentioned multiple times in the Bible. Its most famous historical event, however, is the Siege of Tyre by Alexander the Great in 332 BC.
When Alexander approached Tyre, the city refused to fully submit. It was an island fortress with excellent defenses and a skilled navy. After Alexander built a massive causeway using rubble from the mainland and assembled his own fleet, he was able to conquer Tyre after about seven months. This impressive engineering feat left a lasting mark on the landscape: the causeway altered local coastal currents, causing sediment to accumulate over time. As a result, Tyre is no longer an island but a peninsula, and it remains so today.

With an annual average temperature of around -0.8°C to 0.2°C (about 30.6–32.4°F), Ulaanbaatar is the world’s coldest capital city year-round. It is the only national capital with a sub-zero annual mean temperature, thanks to a combination of its high elevation, extreme continental climate, exposure to Siberian air masses, and temperature inversions that trap cold air in its valley.
The Mongols are historically a nomadic people, so how did Ulaanbaatar become the capital, with roughly half of Mongolia’s population living there? The city’s origins trace back to 1639 as a movable Buddhist monastic center. It changed locations 29 times before settling permanently at its present site in 1778 near the Tuul River and Bogd Khan Mountain, along a key trade route between China and Russia.
When Outer Mongolia declared independence from Qing China in 1911, the city became the capital. After the country became the Mongolian People’s Republic in 1924, it was renamed Ulaanbaatar (“Red Hero”). Despite abandoning communism in 1992, Mongolia has retained the name Ulaanbaatar.

To add to this, why historically is there an Outer and Inner Mongolia? Here’s a post explaining that:
The Inner Mongolia Autonomous Region is the highlighted area. So why is there an independent country called Mongolia (historically Outer Mongolia) alongside this Chinese region called Inner Mongolia?
After the Mongol Empire and Yuan Dynasty collapsed, the Manchu-led Qing Dynasty conquered China and gradually incorporated Mongol territories. The areas closest to China were absorbed earlier and became known as Inner Mongolia. Outer Mongolia, farther north beyond the Gobi Desert, came under control later and retained a stronger nomadic Mongolian identity and greater autonomy.
When the Qing Dynasty fell in 1911, Outer Mongolia declared independence, eventually gaining Soviet support. While China formally recognized this independence in 1946, Inner Mongolia remained under Chinese rule. Due to significant Han Chinese settlement, ethnic Mongols now comprise only about 17–18% of Inner Mongolia’s population. (The final image displays a sign in both the Mongolian script and Chinese characters).
