Answer:
The major problem that the Hispanic Americans in the Southwest faced was that of White settlers taking their land from them.
Step-by-step explanation:
The white settlers that came from far away lands in the east were equipped with advanced weapons and sound warfare techniques. Hence, it was easy for them to forcibly confiscate the lands from the Hispanics and coerce them to fight and die or move elsewhere.
The Hispanic preferred moving to other places after their lands were taken by the white settlers.
