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 USA 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 of America as a nation. Indeed, July 4 is a major national holiday in America and unequivocally thought of as the "birthday" of the entire nation.

Techniques and principles Astrologically, the affairs of a nation are judged from the horoscope set up at the time of its official inauguration or the birth chart of its leader, or various phenomena such as eclipses, lunations, great conjunctions, planetary stations, comets and ingresses. The techiques of the subject were discussed in detail in the 2nd century work of the Alexandrian astronomer Ptolemy, who outlined its principles in the second book of his Tetrabiblos. Ptolemy set this topic before his discussion of individual birth charts because he argued that the astrological assessment of any 'particular' individual must rest upon prior knowledge of the 'general' temperament of their ethnic type; and that the circumstances of individual lives are subsumed, to some extent, within the fate of their community. The third chapter of his work offers an association between planets, zodiac signs and the national characteristics of 73 nations. It concludes with three assertions which act as core principles of mundane astrology: Each of the fixed stars has familiarity with the countries attributed to the sign of its
