Answer: Mexicans lost a lot of territory.
Explanation:
From the perspective of the Mexicans, the Manifest Destiny led to them losing a lot of land. They lost California, New Mexico, Arizona and Texas.
The Manifest Destiny was the primary ideology followed by the United States in the 19th century in which Americans believed it was their right to push the boundaries of the United States from the east coast to the west.
California, Arizona and New Mexico were part of Mexico and were needed for the Manifest Destiny. To achieve this the United States baited Mexico into a war and when they defeated them, they took California, Arizona and New Mexico.
