Agriculture in the prehistoric Southwest
After the Hohokam disappeared, Spanish explorers of the 16th century noted the use of canal irrigation in only two areas of the Southwest: eastern Sonora, primarily practiced by the Opata and Lower Pima, and among the Pueblos of northern New Mexico. Irrigation by the Opata and Pueblos had different objectives. In Sonora, with a long growing season, two crops of maize a year were grown in river valleys. The spring crop during the dry season was dependent upon irrigation; the summer and fall crop during the rainy season utilized irrigation to supplement rainfall. The necessity of irrigation probably required a high level of social organization. In New Mexico, with only one crop of maize per year possible, irrigation was supplemental and the lesser dependence on irrigation implies less social organization than in Sonora.
Acoma Pueblo
Survivors of the Acoma Massacre rebuilt their community 1599–1620. Oñate forced the Acoma and other local Indians to pay taxes in crops, cotton, and labor. Spanish rule also brought Catholic missionaries into the area. The Spanish renamed the pueblos with the names of saints and started to construct churches at them. They introduced new crops to the Acoma, including peaches, peppers, and wheat. A 1620 royal decree created Spanish civil offices in each pueblo, including Acoma, with an appointed governor to take command. In 1680 the Pueblo Revolt took place, with Acoma participating. The revolt brought refugees from other pueblos. Those who eventually left Acoma moved elsewhere to form Laguna Pueblo.
