Hi, I want to learn about Mexico History?
Mexico encouraged people to migrate to Texas to expand their Frontier.
Was there any reason behind this migration?
They wanted to stabalize and develop the frontier.
What more I can learn on the history?
One of their leaders was Obregon. He was reelected in 1928 but was assassinated before he could even assume his seat.
What is Obregon about, I have no idea?
Obregon is his name?
I meant what sort of organization was Obregon in for him to be assassinated, like what caused it?
Sorry about that misunderstanding. I do not have anymore information on Obregon. Other than He became the leader after Carranza was assassinated. Obregon was a revolutionary hero.
Its okay. Shall we discuss the government and politics?
Mexico's National Geography and statistics institute estimated in 2014 that one fifth of Mexicans were involved in some sort of crime.
Thanks a lot. That's all I need for now
You are welcome!
