area as early as 300 BC. Whether Hohokam culture was unified politically remains under controversy. Hohokam culture may have just given unrelated neighboring communities common ground to help them to work together to survive their harsh desert environment. Mogollon The Mogollon culture () was an ancient Pre-Columbian culture of Native American peoples from Southern New Mexico and Arizona, Northern Sonora and Chihuahua, and Western Texas. The northern part of this region is Oasisamerica, while the southern span of the Mogollon culture is known as Aridoamerica. The Mogollon culture was one of the major prehistoric Southwestern cultural divisions of the Southwestern United States and Northern Mexico. The culture flourished from , to c. 1450 CE or 1540 CE, when the Spanish arrived. Sinagua The Sinagua culture was a Pre-Columbian culture that occupied a large area in central Arizona from the Little Colorado River, near Flagstaff, to the Verde River, near Sedona, including the Verde Valley, area around San Francisco Mountain, and significant portions of the Mogollon Rim country, between approximately 500 CE and 1425 CE. Besides ceremonial kivas, their pueblos had large "community rooms" and some featured ballcourts and walled courtyards, similar to those of the Hohokam culture. Since fully developed Sinagua sites emerged in central Arizona around 500 CE, it is believed they migrated from east-central Arizona, possibly emerging from the Mogollon culture. Spanish and Mexican Arizona The history of Arizona as recorded by Europeans began in 1539 with the first documented exploration of the area by Marcos de Niza, early work expanded the following year when Francisco Vásquez de Coronado entered the area as well. The Spanish established a few missions in southern Arizona in the 1680s by Father Eusebio Francisco Kino along the Santa Cruz River, in what was then the Pimería Alta region of Sonora. The Spanish also established presidios in Tubac and Tucson in 1752 and 1775. The area north of the Gila River was governed by the Province of Las California under the Spanish until 1804, when the Californian portion of Arizona became part of Alta California under the Spanish and Mexican governments. American Arizona Starting in 1853, the entirety of present-day Arizona was part of the New Mexico Territory. In 1849, the California Gold Rush led as many as 50,000 miners to travel across the region, leading to a boom in Arizona's population. In 1850, Arizona and New Mexico formed the New Mexico Territory.
