Check Explanation.
Step-by-step explanation:
Currently, Texas is one of the largest state in the United States of America, second largest to be precise. But before they became a state in the United States of America they were once in Mexico.
Texas got their independence from Mexico to join the United States of America and the following are the reasons;
(1). Many people came from the United States and settled in Texas. As at that time, slavery is legal in the United States while it is not in Mexico. The people that came from the United States knew that one day, the Mexico government will seize their slaves, so they had to fight for independence.
(2). The need for Texas to be a state on its own.
(3). The numbers of American settlers are more than the native Texans.
(4). The belief called the "manifest destiny'' that is to say the United States of America should ''own" Mexico.
