During the period of the Republic of Texas (1836-1845), the issue of slavery was one of the main sources of political conflict.

The expansion of slavery into new territories was a contentious issue at the time, and many Texans saw the defense of slavery as a key part of their identity and way of life. This led to conflicts with the federal government, which was increasingly opposed to the expansion of slavery, as well as with neighboring Mexico, which had abolished slavery in 1829. The issue of slavery and its expansion would continue to be a major source of conflict in the United States, ultimately leading to the Civil War.
