Did Texas have slaves in the 1800's?

Yes texas did have slavesn

Explanation:The history of slavery in Texas, as a colonial territory, later Republic in 1836, and U. S. state in 1845, had begun slowly, as the Spanish did not rely on it for labor during their years in Spanish Texas. The use of slavery expanded in the mid-nineteenth century as British-American settlers primarily from the Southeastern United States crossed the Mississippi River and brought slaves with them. Slavery was present in Spanish America and Mexico prior to the arrival of American settlers, but it was not highly developed.

The issue of slavery became a source of contention between the Anglo-American (called that because they spoke English) settlers and Spanish governors. The governors feared the growth in the Anglo-American population in Texas, and for various reasons, by the early 19th century, they and their superiors in Mexico City disapproved of expanding slavery. In 1829 the Guerrero decree conditionally abolished slavery throughout Mexican territories. It was a decision that increased tensions with slaveholders among the Anglo-Americans.
