The city of Temecula, forming the southwestern anchor of the Inland Empire region, is approximately 58 miles (93 km) north of downtown San Diego and 85 miles (137 km) southeast of downtown Los Angeles. Temecula is bordered by the city of Murrieta to the north and the Pechanga Indian Reservation and San Diego County to the south. Temecula had a population of 100,097 during the 2010 census and an estimated population of 114,761 as of July 1, 2019. It was incorporated on December 1, 1989.
The area was inhabited by the Temecula Indians for hundreds of years before their contact with the Spanish missionaries (the people are now generally known as the Luiseños, after the nearby Mission San Luis Rey de Francia). The Pechanga Band of Luiseño believe their ancestors have lived in the Temecula area for more than 10,000 years, though ethnologists think they arrived at a more recent date. In Pechanga history, life on Earth began in the Temecula Valley.
