The correct answer is B. The conflict that existed in Texas between Mexicans and American settlers in the mid 1800s was that slavery was outlawed in Texas, making American settlers angry.
In 1823, Mexico prohibited the sale or purchase of slaves and required the children of the slaves to be released when they turned 14 years old. Any slave that was introduced to Mexico either sold or exchanged would be released. In 1829, slavery was officially prohibited.
Many of the American settlers owned slaves. On April 6, 1830, Mexican President Anastasio Bustamante ordered Texas to comply with the proclamation of emancipation or face military intervention. To flout the law, many settlers turned their slaves into servants hired for life. Others simply called their slaves servants without legally changing their status.
Texas formally declared its independence on March 2, 1836. The new constitution of Texas especially allowed slavery and specified that no African could live in the territory without consent of the congress.
