There are 50 states in the United States. Each state has its own capital city, which serves as the seat of state government. Additionally, Washington D.C. is the federal capital of the entire country, but it is not part of any state.

Many people mistakenly assume the largest city in a state is its capital. Common mix-ups include: New York (capital is Albany, not NYC), California (Sacramento, not LA or SF), Texas (Austin, not Houston), Florida (Tallahassee, not Miami), Illinois (Springfield, not Chicago), and Washington (Olympia, not Seattle).

Phoenix, Arizona is the largest state capital by population, with over 1.6 million residents. It's also the only U.S. state capital with a population exceeding 1 million. Other populous state capitals include Austin (Texas), Columbus (Ohio), and Indianapolis (Indiana).

Montpelier, Vermont is the smallest state capital in the U.S., with a population of only about 8,000 people. Despite its small size, it's a charming city rich in history. Other small capitals include Pierre (South Dakota) and Augusta (Maine).

State capitals were often chosen for geographic centrality, historical significance, or political compromise rather than population size. For example, Sacramento was chosen over San Francisco because of its central location in California during the Gold Rush era. Many capitals were established in the 18th and 19th centuries when population patterns were very different from today.
