who were the 3 people involved in the acquisition of territory for Mexican Cession?

The three people involved in the acquisition of territory for Mexican Cession were:

1. James K. Polk: He was the President of the United States from 1845 to 1849 and played a significant role in expanding the country's territory. Polk's administration was focused on manifest destiny and the acquisition of western territories.

2. John Slidell: He was a diplomat and politician who was sent by President Polk to Mexico in 1845 in an attempt to negotiate the purchase of California and New Mexico. Slidell's mission was ultimately unsuccessful, as Mexico refused to sell the territories.

3. Zachary Taylor: He was a general in the United States Army and became a national hero during the Mexican-American War. Taylor's military victories in the battles of Palo Alto, Resaca de la Palma, and Monterrey played a crucial role in the US acquisition of Mexican territory, leading to the eventual Mexican Cession through the Treaty of Guadalupe Hidalgo in 1848.
