Corn
has been a domestic plant for so long that it cannot survive without human
care. It appears in the archeological record of southern Mexico and highland
Central America about 7,200 years ago. By then, corn already had its present
characteristics. Subsistence farmers in Mexico and Central America have
planted corn since that time.

Corn
spread south into the lowland tropics of Central America shortly after
its first domestication. From there, before 5,000 B.C., it found its way
to the coasts of Ecuador and Peru. All of the high civilizations that arose
in North and South America planted corn as their principal crop. Throughout
Mexico and Central America, corn and corn gods played a dominant role in
native religion. Present holidays in that region often date back to festivals
in honor of "The Giver of Corn."
Corn cultivation made its way north much more slowly. It was first grown north of the Valley of Mexico about the beginning of the Christian Era. It reached the upper Rio Grande Valley about 700 A.D. There, people known as the Anasazi built centers like Pueblo Bonita (Chaco Canyon, NM) and Mesa Verde (CO), Hovenweep (UT) and Canyon de Chelly (AZ).
Corn
reached the Mississippi Valley and Atlantic Coast of North America within
the next 150 years. By 1100 A.D., an extensive civilization known as the
Mississippian culture, based on corn planting, had arisen there. The areas
was cropped almost as intensively as today. Vast areas were devoted to
farming, which supported between 15 and 20 million people. The dense forests
found in the Mississippi Valley by 18th century European colonists were
all secondary growth forests. They came after the Mississippian civilization
collasped from depopulation by European diseases introduced in 1540 by
the DeSoto expedition.
Corn gave Mississippian rulers the energy and populations necessary to build large cities such as Cahokia (IL), Chucalissa (TN) and St Louis (MO). Their farms extended from horizon to horizon. Their corn fields occupied most of the arable land. The area of the Southeastern States also produced a similar high culture based primarily on cultivation of corn. The cities of Etowah (GA) and Moundville (AL) were among more than 1,100 different centers built between the arrival of corn about 950 AD and the catastropic collapse of native populations in after 1540.
Corn cultivation extended as far west as the four corners
region of New Mexico, Arizona, Colorado and Utah. It was the staple food
of the Anasazi,
Mogollon
and Hohokam
cultures in the Southwest. It was an important crop to the Mandans of North
Dakota, the nations of the Iroquois confederation in New York and the Great
Lakes Region. From the Central Andes and Amazon Basin to Northeastern Canada
and the American Great basin, native subsistence farmers grew corn as their
principal source of food energy.
Corn
was the Native American's greatest contribution to world agriculture. Corn
has kept pace with our need for food for an ever expanding population.
