Final answer:
Article X of the Treaty of Guadalupe Hidalgo promised land rights to Mexicans in Texas, but its removal led to dispossession of their lands.
Step-by-step explanation:
If Article X had not been removed from the Treaty of Guadalupe Hidalgo, 4) Mexicans living in Texas would have been able to keep their land. The Treaty of Guadalupe Hidalgo initially guaranteed that Mexican and Spanish land deeds and grants would be recognized by the United States, allowing resident Mexicans to retain ownership of their lands. However, subsequent amendments and interpretations weakened this provision, leading to widespread dispossession of land from Mexicans and Mexican-Americans. The removal of Article X exacerbated this by officially allowing the questioning and displacement of Mexican landownership.
