What was the time period known as the Mexican Sovereignty Period in Texas?

The Mexican Sovereignty Period in Texas is accurately defined as the time from 1821 to 1836. This period began when Mexico achieved independence from Spain in 1821 and encompassed the years leading up to the Texas Revolution in 1836 when Texas declared its independence from Mexico.

During this time, the new Mexican government implemented land grants to encourage settlement, leading to an influx of Anglo settlers into the region. These settlers often brought different cultural and political expectations that eventually contributed to conflicts with the Mexican authorities. The era was marked by significant changes in governance, land policies, and the social fabric of Texas society, setting the stage for the tensions that culminated in the revolution.

In contrast, the other time periods mentioned do not accurately reflect the Mexican Sovereignty Period. The time frame before 1821 is associated with Spanish rule, while the periods after 1836 relate to Texas independence and further developments leading to eventual annexation by the United States.
