Why the Americans start to move to Texas in the S's?

Answer 1

Spain was unable to persuade its own citizens to move to remote Texas. Spain then offered generous land grants in Texas to Americans who were Catholic, industrious, and willing to become Spanish citizens. Mexico continued this policy in 1921 by granting contracts to empresarios who would settle in Texas and supervise selected, qualified immigrants.

Americans were attracted to Texas because of inexpensive land. Most American settlers thought that the United States would buy eastern Texas from Mexico which would stimulate Immigration and provide buyers for their land, increasing the value of the land.

Also, Mexico and the United States had no reciprocal agreements enabling creditors to collect debts or to return fugitives so many farmers who had defaulted on loans and faced seizure of their property, and, possibly, debtor's prison, headed for Texas where they could start over.
