Explanation:

The Caddo were primarily villagers and

farmers, and their culture had a class

system as part of their social

structure. They lived in grass houses

around fifteen feet tall and twenty to

fifty feet in diameter, framed with

poles in a domed or conical shape and

covered with grass thatch. Their

territory included communities of

isolated farms, small villages and

some larger villages.

The Caddo people developed a

successful agricultural economy based

on growing maize, beans,

watermelons, pumpkins, figs, tobacco,

and squash. By about A.D. 1300 most

Caddoan groups were consuming

large amounts of maize, and this plant

was clearly the most important food

source for them time. They also

supplemented their diet by hunting,

and deer was their most important

game animal. The Caddoes were also

excellent fishermen, using trotlines, a

fishing line loaded with baited hooks

across streams. Being close to the

plains they acquired horses sometime

in the 17th century.

Interestingly, Caddos’ traced their

descent through the maternal line

rather than the paternal. The xinesi

inherited a position of spiritual

leadership, the caddi, the inherited

position of principal headman of a

community. The xinesi were

responsible for communication with

the supreme god and meditation.

While caddi ayo were responsible for

religious leadership and decisionmaking influence between villages

and leading important rites, such as

harvest and naming rights. The

Caddoes ruled with a well organized

government system.

The Caddo had early contact with

Spanish Conquistadores under

Hernando de Soto in 1541. The

Caddo people traded fur, guns,

horses, and other items to

Europeans and other Indians, and

developed new trade and economic

networks. The economic trade

between the Caddo groups and

Europeans sped up the process of

the Caddo people adopting the

cultural traits and social patterns of

the Europeans.

By the early 1840s, all Caddo groups

had moved to the Brazos River area

to escape colonization efforts. They

remained there until they were

placed on the Brazos Indian
