Answer 4

When the United States made the Louisiana Purchase in 1803, the land west to the Rio Grande was included in the claim. When Mexico became independent, the government approved that grant of Stephen F. Austin for the settlement his father had begun under Spanish rule. A coup by General Antonio López de Santa Anna changed the atmosphere, with Austin being imprisoned. Texas formed a provisional government in 1835, declaring independence in 1836, which was followed by the siege of the Alamo, in which Sam Houston captured Santa Anna, securing the independence of the Republic of Texas. Texas became the 28th state to enter the union on 29 December 1845.
