The Purépecha Empire, also known by the term Iréchikwa, was a polity in pre-Columbian Mexico. Its territory roughly covered the geographic area of the present-day Mexican state of Michoacán, as well as parts of Guanajuato, Guerrero, and Jalisco. At the time of the Spanish conquest, it was the second-largest state in Mesoamerica. The state is also known as the Tarascan Empire, an exonym often considered pejorative by the Purépecha people.

Michoacán, formally Michoacán de Ocampo, officially the Estado Libre y Soberano de Michoacán de Ocampo, is one of the 31 states which, together with Mexico City, comprise the Federal Entities of Mexico. The state is divided into 113 municipalities and its capital city is Morelia. The city was named after José María Morelos, a native of the city and one of the main heroes of the Mexican War of Independence.
