Yucatán yo͞okətăn´, –kätän´ [key], state (1990 pop. 1,362,940), 14,868 sq mi (38,508 sq km), SE Mexico, occupying most of the northern part of the Yucatán peninsula. It lies between Campeche and Quintana Roo. The principal industry is tourism and the cultivation and preparation of henequen—mostly exported to the United States. Citrus production has gained in importance in recent years, and textile production, tobacco and other farming, and fishing are also important. Roads and rail lines connect many of the larger towns with the capital, Mérida. By 300 BC, and until Columbian times, Yucatán was populated by the Maya. Cortés came to Yucatán in 1519. It became a state when Mexico won independence (1821) but seceded from 1839 to 1843. There were severe political uprisings in 1847 and in 1910. Several of the most famous Mayan ruins, including Tulúm, Chichén Itzá, and Uxmal, are located here.
