After that the people of Texas wanted to become a part of the United States, Who they would be under the leadership of the president , Sam Houston. But with strong approval, They signed the legislation which made Texas an American state on December 29, 1845. The politics in the United States issued over whether or not Texas should be admitted as a slave or a free state. In the end it was admitted to the United States as a slave state.
Like it said in the video the Americans wanted to move into mexico but they said yes as long as they followed the rules which are. 1: They must become Mexican citizens. 2: Must become catholic. 3: NO SLAVES at all. But they did not follow all the rules and they broke the most important rule of all NO SLAVES. But the Americans continued to do it so after 7 years of dealing with the Americans the Mexicans got mad and told them to take it very seriously this time because it was a complete NO for slaves and completely banned slaves at all costs. Then they finally listened.
