when were the first american settlements for the texas territory?

Answer 1

"American Indian tribes who once lived inside the boundaries of present-day Texas include Apache, Atakapan, Bidai, Caddo, Comanche, Cherokee, Kiowa, Tonkawa, Wichita, Hueco and the Karankawa of Galveston. Currently, there are three federally recognized Native American tribes which reside in Texas: the Alabama-Coushatta Tribe of Texas, the Kickapoo Traditional Tribe of Texas, and the Ysleta Del Sur Pueblo of Texas."

"On November 6, 1528, shipwrecked Spanish conquistador Álvar Núñez Cabeza de Vaca became the first known European in Texas.[12] Most of Texas was immediately claimed by Spain (mostly western Texas) as part of the Spanish dominions of New Spain.[13] However, France took advantage of Spain's failure to settle the land and in 1685 established Fort St. Louis and claimed most of Texas. The first Spanish colonization did not come until a few years after Fort St. Louis, as Spain was spurred by France to enforce its claims."

"In the 1800s, two main ethnic groups settled the land: Tejanos and eventually Anglo Americans. Smaller numbers of Europeans also came. Moses Austin bought 200,000 acres (800 km²) of land of his choice, and moved to San Antonio in August of 1821.[14] His son, Stephen F. Austin, joined him." "On January 3, 1823, Stephen F. Austin began a colony of 300 Anglo American families known as the "Old Three Hundred" along the Brazos River, after Austin was authorized to do so by Governor Antonio María Martínez." "Meanwhile, more Tejanos were also settling in Texas, and as Antonio Menchaca writes in "Memoirs" in 1907, many Tejanos were already desirous of joining the United States. Tejanos were mostly full-blooded Spanish immigrants, few partly or entirely of American Indian heritage as most Mexicans south of the Rio Grande were."

"In the years following the Louisiana Purchase and the acquisition of New Orleans by the U.S., American settlers had begun to move westward into Mexican claimed territory. Some settlers were active filibusters, who sought the long-term annexation of the area by the U.S. In 1812–13, the Gutiérrez-Magee Expedition attempted to separate Texas from the Spanish Empire."

"The Rio Grande and South Texas areas had a history of independence movements by the local Mexican and especially Tejano population, on account of unitary and perceived dictatorial and unconstitutional practices by the central Mexican government. Northern and East Texas, meanwhile, remained largely in the hands of Native American tribes, some of whom were hostile to Mexican rule." ("Mexican Texas"', Wikipedia)
