The District of Columbia was created in 1790, when Congress passed the Residence Act, which designated a new federal capital city. And, let me tell you, it was a bit of a wild west situation back then, with landowners and politicians fighting over who would get to build the new city. In the end, they decided to create a special district that would be controlled by the federal government, rather than any individual state.
Today, the District of Columbia is home to over 700,000 people, including politicians, lobbyists, and lots of tourists. And, if you ever visit, you'll notice that the city is filled with landmarks and monuments, like the White House, the Capitol Building, and the Lincoln Memorial. It's like a real-life Game of Thrones set, but instead of swords and dragons, there are suits and briefcases.
