The United States is a federal republic founded with the Declaration of Independence in 1776, which expanded across North America and acquired overseas territories after 1898. After World War II it became a global superpower. Whether its global power makes it an "empire" is debated, and Wikipedia's "List of empires" marks it as disputed.
