Explanation:

There were several causes of the conflict between the American settlers and Mexico. First, Mexico feared that they would lose Texas to the United States, so they started enforcing laws that had been ignored. Then, Santa Anna gained power and became a dictator. There were rumors that Santa Anna wanted to drive Americans out of Texas. Americans wanted to overthrow Santa Anna, so this started fighting.
