Mundane astrology, also known as political astrology, is the branch of astrology dealing with politics, the government, and the laws governing a particular nation, state, or city. The name derives name from the Latin term mundus, 'world'.
Certain countries have astrological charts (or horoscopes) just like a person is said to in astrology; for example, the chart for the United States is widely thought to be sometime during the day of July 4, 1776, for this is the exact day that the Declaration of Independence was signed and made fully official, thus causing the "birth" of the United States as a nation. Indeed, July 4 is a major national holiday in America and unequivocally thought of as the "birthday" of the entire nation.
