Morelia is the capital and most populous city of the Mexican state of Michoacán. Situated in the Guayangareo Valley in the north-central part of the state, it is the municipal seat of the municipality of Morelia. The main pre-Hispanic cultures here were the Purépecha and the Matlatzinca, but no major cities were founded in the valley during this time. The Spanish took control of the area in the 1520s. The Spanish under Viceroy Antonio de Mendoza founded a settlement here in 1541 with the name of Valladolid, which became rival to the nearby city of Pátzcuaro for dominance in Michoacán. In 1580, this rivalry ended in Valladolid's favor, and it became the capital of the viceregal province. After the Mexican War of Independence, the city was renamed Morelia in honor of José María Morelos, who hailed from the city. In 1991, the city was declared a UNESCO World Heritage Site for its well-preserved historical buildings and layout of the historic center. It is tradition to name people born on September 30 after the city.
