The effects of the Mexican-American War include:

1. Treaty of Guadalupe Hidalgo: The war concluded with the signing of the Treaty of Guadalupe Hidalgo in 1848, through which Mexico ceded a significant portion of its territory to the United States. This territory included present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado, Wyoming, Kansas, and Oklahoma.

2. Expansion of the United States: The acquisition of vast new territories through the war greatly extended the territorial boundaries of the United States, leading to a significant increase in its size and population.

3. Border disputes and tensions: The new border between the United States and Mexico, established by the Treaty of Guadalupe Hidalgo, led to subsequent border disputes and tensions, which still persist to some extent today.

4. Mexican-American relations: The war severely strained relations between Mexico and the United States, creating a sense of bitterness and hostility that lingered for decades. This strained relationship impacted diplomatic, economic, and cultural interactions between the two countries.

5. Impact on Slavery: The debate over the expansion of slavery into newly acquired territories from Mexico exacerbated tensions between the North and South in the United States. This ultimately contributed to the growing divide and eventually led to the American Civil War.

Overall, the Mexican-American War significantly shaped the geography, politics, and dynamics of North America, leaving a lasting impact on both Mexico and the United States.
