The Akokisa were the indigenous tribe that lived on Galveston Bay and the lower Trinity and San Jacinto rivers in Texas. They are regarded as a band of the Atakapa Indians, closely related to the Atakapa of Lake Charles, Louisiana.
Álvar Núñez Cabeza de Vaca wrote about the Akosisa in 1528, calling them the "Han." An early reported encounter with the Akokisa by a European person was in 1719 when Simars de Bellisle, a French officer, was held captive by the Akokisa until 1721. His account of his captivity provides some information about Akokisa culture.
Around the 1750s the Akokisa were divided into five village groups. Some Akokisa people entered the San Ildefonso Mission in 1748-9 but left in 1755. That mission was abandoned and replaced by Nuestra Señora de la Luz Mission, built in 1756-57 on the Trinity River, to serve the Akokisa and Bidais tribes.
In 1805, the Akokisa were reduced to two villages. One coastal village lay between the Sabine and Neches Rivers; the other was on the west side Colorado River. The Akokisas may have been absorbed into other tribes at the wake of the Texas Revolution of 1835-6.
In 1947, Orobio counted about 300 families for each village, an estimated total between 1,200-1,250.
The name Akokisa is of unknown origin, although John R. Swanton has speculated that the name may be from the Atakapa word icāk meaning "person". The Akokisa have also been known by the following names (and spellings): Accockesaws, Accokesaus, Accokesaws, Aco-ke-sas, Arkokisa, Horcoquisa, Ocosaus, Orcoquisa(s), Orcoquisacs, Orcoquizas.
Akokisa people lived in settled villages and built airy structures to cope with their warm climate. Their homes were beehive-shaped and thatched with grass or palmetto leaves. A hearth would be located in the center of the floor with a smokehole in the ceiling. During summer months, an Akokisa would sleep in a Chickee, a raised platform with a thatched roof and open sides. Beds were made of straw, covered with animal skins.
Both men and women decorated their bodies and faces with tattoos.
The Akokisa, like the Atakapa, practiced cannibalism, which may have been connected to their religious beliefs. Cannibalist feasts were described by Simars de Bellisle, who observed them firsthand.
Black drink was used for purification in certain ceremonies.
They are reported to have grown "superfine" maize. Tubers of the Greenbrier vine provided meal for baking and cooking. During warm seasons they ate bird eggs, fish, shellfish, and American lotus rhizomes and seeds; during cold seasons they moved further inland and hunted deer, bear, and buffalo. Horses were used to hunt buffalo. Tanned deer hides and bear fat were their primary commercial exports.
Almost nothing is known about their kinship systems, life cycle, or marriage customs.
The Akokisa language is extinct and virtually unknown.
Swanton claimed that the Akokisa spoke a language related to Atakapa based on the similarity of a vocabulary of 45 words ascribed to the Akokisa collected by Captain Jean Béranger in 1721 on Galveston. However, there is no clear evidence that this document actually represents the language of Akokisa (Béranger provides a tribal designation for the vocabulary).
Sibley also reported that they had their own language "peculiar to themselves" and used sign language to communicate with other Indians (also reported for other peoples in eastern Texas). He did not connect them with the Atakapa.
Only two Akokisa words have been found in Spanish records: Yegsa meaning "Spaniard(s)" and Quiselpoo, a female name.
