Final answer:
False, Stephen Austin did not lose his contract to settle Texas after Mexico gained independence from Spain; he solidified his position, reflecting Mexico's continued policy to encourage settlement.
Step-by-step explanation:
The statement that Mexico's Independence from Spain caused Stephen Austin to lose his contract to settle in Texas is false. After Mexico gained independence from Spain in 1821, Stephen Austin was able to take control of his father's grant to settle in Texas. Mexico continued the Spanish policy of encouraging settlement in the region of Coahuila y Texas.
Stephen F. Austin led the first 300 families into Texas, also known as the Old Three Hundred, and played a pivotal role in Texas's colonization and path to independence. Despite Mexico's initial welcome to American settlers, tensions grew over issues such as slavery, which Mexico outlawed, and governance, climaxing when the Texan Revolution culminated in 1836 with the Battle of San Jacinto and the creation of the Republic of Texas.
