What is Oktoberfest?

Oktoberfest (called "Wiesn" in German) is the largest folk festival in the world. In 2023, 7.2 million visitors drank close to 2 million gallons of beer, making it the most-attended Oktoberfest ever.

 

The first Oktoberfest was held in 1810 to celebrate the marriage of Prince Ludwig and Princess Therese von Sachsen-Hildburghausen. That year, five days of performances, food, and music culminated with a horse race. Since that first year, it’s grown considerably. It’s also spread far beyond Germany, with celebrations in many countries outside of Europe.

 

Various traditions have been added throughout the years, highlighted by its roasted chicken vendors (still an integral part of Oktoberfest), carnival rides, and the now-ubiquitous glass steins for beer, all of which have made the festival more popular than ever. Beer is integral to Oktoberfest, but only beers from one of six designated breweries in the city of Munich can be officially called “Oktoberfestbier.”

Global Tensions

 

An explainer on the Cold War

The Cold War was a global competition (watch animated map) for power and influence between the United States, a capitalist democracy, and the Soviet Union, a state-controlled socialist system, from 1945 to 1991, sparked by tensions over how to shape the post-World War II order.
 

The conflict was defined by ideological rivalry, massive military spending, and a nuclear arms race that brought the world to the brink of thermonuclear war. Though the two superpowers never engaged in direct combat—hence, the war remained “cold”—they waged proxy wars on nearly every continent.
 

The Cold War concluded in 1991 with the collapse of the Soviet Union after losing control of much of its territory in the preceding years. However, its legacy is still visible today in renewed great-power rivalries, ongoing nuclear tensions, and the resurgence of strongly centralized governance.

Household Leverage

 

Mortgages, 101

Mortgages are a type of property loan that financial institutions, such as banks and credit unions, can offer when a prospective buyer decides against paying a property’s full cost in cash. In 2024, 74% of homebuyers took out a mortgage. Debt owed on mortgages made up about 70% of US consumer debt as of 2025.

 

People have been formally lending money in exchange for interest and collateral since the fifth century BCE. But the term “mortgage” wasn’t adopted until around the 11th century in Britain. 

 

In the US, individuals loaned money to each other to buy property before institutional private financing was popularized in the 1800s. Mortgage banks were created in the 1870s to provide loans financed by mortgage-backed bonds.
