Agrarian society
Agrarian society were preceded by hunter and gatherer and horticultural societies and transition into industrial society. The transition to agriculture, called the Neolithic Revolution, has taken place independently multiple times. Horticulture and agriculture as types of subsistence developed among humans somewhere between 10,000 and 8,000 years ago in the Fertile Crescent region of the Middle East. The reasons for the development of agriculture are debated but may have included climate change, and the accumulation of food surplus for competitive gift-giving. Most certainly there was a gradual transition from hunter-gatherer to agricultural economies after a lengthy period when some crops were deliberately planted and other foods were gathered from the wild. In addition to the emergence of farming in the Fertile Crescent, agriculture appeared in: by at least 6,800 B.C.E. in East Asia (rice) and, later, in Central and South America (maize and squash). Small-scale agriculture also likely arose independently in early Neolithic contexts in India (rice) and Southeast Asia (taro). However, full dependency on domestic crops and animals, when wild resources contributed a nutritionally insignificant component to the diet, did not occur until the Bronze Age.
Agriculture on the prehistoric Great Plains
Squash and beans were cultivated in what is now the United States, independent of Mesoamerica. Maize is a tropical crop first cultivated in Mexico which found its way northward to the United States over thousands of years. Maize agriculture began on the Great Plains by AD 900, initiating the Southern Plains villagers period of western Oklahoma and Texas. It probably came about as an extension westward and northward of the Caddoan cultures of eastern Texas. The Plains Village culture consisted of hamlets and semi-permanent villages along major rivers such as the Red, Washita, and Canadian. Subsistence was a combination of agriculture and hunting. A drying climatic trend beginning AD 1000 or 1100 may have tipped the subsistence scale more toward hunting and less toward a dependence upon agriculture. The Antelope Creek Phase of Plains villagers, dated from AD 1200 to 1450 in the Texas panhandle was influenced by the Southwestern Pueblo people of the Rio Grande valley in New Mexico.
The contemporaneous Apishapa culture of southeastern Colorado depended mostly upon hunting. The historic descendants of the Southern Plains villagers are possibly the Wichita and Pawnee Indians.
