, the Spanish Governor, placed Fray Francisco de Ayeta as administrator of the refugee camp of those fleeing Popé's rebellion in 1680. The refugee camp and mission was placed approximately three miles south of the Rio Grande at the time. The Rio Grande was prone to both flooding and silt deposit.
Resettlement
The settlement and associated mission moved several times over the next few hundred years. In 1691, the original refugee mission was replaced by an adobe structure. A flood in 1740 washed away that mission. It was rebuilt on higher ground four years later. The Tigua of Ysleta were among the most faithful Christian converts in the area and the Spanish were keen to keep the settlement healthy and vibrant. In the period between 1829 and 1831, the river moved much further south than usual. In 1836, the new country of Texas claimed the new channel of the Rio Grande as the boundary. In 1848, with the ratification of the Treaty of Guadalupe Hidalgo, Ysleta was ceded to the United States. The mission was a stop on the Butterfield Overland Mail trail from 1858 to 1861.
The neighboring community and county seat of San Elizario was a center of Hispanic influence in an increasing Anglo- dominated post-Civil War period. In 1873, Ysleta made a bid to become the county seat, but the elections were ignored or inconclusive until 1878, after the Salt War period. In response, the people of Ysleta incorporated as a Texas city in 1880. There were internal disputes as to whether the tax burden was worth the status as a city. There was also much opposition from the growing community of El Paso as to whether an "Indian" city should be the county seat. The railroad did not come to Ysleta, and in a strongly disputed election in which counted votes were nearly three times the number of voters, the county seat was moved to El Paso in 1883. The town government dissolved in 1895.
Fire
A chemical fire in 1907 damaged the Ysleta Mission. In 1916, the Rio Grande was dammed and the area was heavily irrigated. The resulting rise in the water table brought salt to the surface and the land became suitable for only salt-tolerant crops such as cotton.
Annexation
In 1955, El Paso annexed Ysleta, although residents voted against the change. Ysleta was allowed to keep its own school district, although that required an appeal to the Supreme Court.
