The event that led the Oregon Territory to become a part of the U.S was the Oregon Treaty of 1846. This treaty was negotiated between the United States and Britain, as both countries claimed ownership of the territory. Under the agreement, the border between the U.S and the British-held territories was set at the 49th parallel, from the Rocky Mountains to the Pacific Ocean. This led to the incorporation of the Oregon Territory into the United States.

The Mexican Cession became a part of the U.S in 1848. This was a result of the Treaty of Guadalupe Hidalgo, which ended the Mexican-American War. Under the treaty, Mexico ceded a vast territory to the United States, including present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming. The Mexican Cession greatly expanded the territorial size of the United States.

Three key people involved in allowing the Mexican Cession to become a part of the U.S are:

1. James K. Polk: As the President of the United States from 1845 to 1849, Polk played a crucial role in initiating the Mexican-American War and subsequently negotiating the Treaty of Guadalupe Hidalgo. He advocated for territorial expansion and the acquisition of the Mexican Cession.

2. Nicholas Trist: Trist was a diplomat and negotiator who represented the United States during the negotiations of the Treaty of Guadalupe Hidalgo. Despite conflicting instructions from President Polk, Trist took the initiative and successfully negotiated the treaty, which included the Mexican Cession.

3. Winfield Scott: Scott was a General in the United States Army and played a significant role in the Mexican-American War. He led the U.S forces to victory in several key battles, including the capture of Mexico City. His military successes in the war contributed to the U.S position of strength in negotiations and the eventual acquisition of the Mexican Cession.

The event that led to the Mexican Cession becoming a part of the U.S. was the Mexican-American War. The war began in 1846 when tensions arose over the disputed border between Texas (which had recently been admitted to the Union) and Mexico. The United States launched a military campaign, invading and capturing several territories controlled by Mexico, including present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming.

The decisive battles and victories by the U.S. forces, led by generals like Winfield Scott, played a significant role in Mexico's defeat. The war concluded with the signing of the Treaty of Guadalupe Hidalgo in 1848. As a result of this treaty, Mexico ceded the Mexican Cession territory to the United States, formally establishing it as a part of the U.S.

The Gadsden Purchase became a part of the U.S. in 1854. The Gadsden Purchase was a treaty signed between the United States and Mexico, and it involved the acquisition of a strip of land in present-day southern Arizona and southwestern New Mexico. This purchase was made to facilitate the construction of a transcontinental railroad. The treaty was negotiated by James Gadsden, the U.S. Minister to Mexico, and was ratified by the U.S. Senate in 1854.

Three key people involved in allowing the Gadsden Purchase to become a part of the U.S are:

1. James Gadsden: James Gadsden was the U.S. Minister to Mexico at the time of the Gadsden Purchase negotiations. He played a crucial role in negotiating the purchase of the territory from Mexico. Gadsden's diplomatic efforts led to the signing of the treaty that resulted in the acquisition of the land.

2. Franklin Pierce: Franklin Pierce was the President of the United States from 1853 to 1857. He strongly supported the expansion of U.S. territory and saw the Gadsden Purchase as vital for completing a southern transcontinental railroad. Pierce authorized the negotiations with Mexico and eventually signed the treaty, making the Gadsden Purchase a part of the U.S.

3. Santa Anna: Antonio López de Santa Anna was the President of Mexico at the time of the Gadsden Purchase negotiations. Although Santa Anna's role was not direct in the acquisition, his agreement to sell the territory was crucial. Santa Anna faced domestic challenges and financial difficulties, which influenced his decision to sell the land to the United States.
