Santa Fe de Nuevo México followed by New Mexico Territory
Mexican territory
The province remained in Spanish control until Mexico's declaration of independence in 1821. Under the 1824 Constitution of Mexico, it became the federally administered Territory of New Mexico.
The part of the former province east of the Rio Grande was claimed by the Republic of Texas, which won its independence in 1836. This claim was disputed by Mexico. In 1841, the Texans sent the Texan Santa Fe Expedition, ostensibly for trade but with hopes of occupying the claimed area, but the expedition was captured by New Mexican troops under New Mexico governor Manuel Armijo.
