What were the accomplishments of James K. Polk during his presidency?

Answer 1

James K Polk set plans to expand the territories into Mexico. He declared war by alleging that he had a right to land that Mexico had already claimed, despite that the person who signed it was no longer Mexico's leader, and was currently being imprisoned by the new Mexican government.

In Mexico, this war is referred to as "The American Invasion of Mexico."

America ultimately won the war, and decided to take what is now the Southwest. Soon afterwards gold was found in California, starting the California Gold Rush, and finally completing Columbus's 356 year long goal.

The United States gained 525,000 square miles of western territory by winning the Mexican war. He added territory that now composes of Arizona,Utah,Nevada,California,Oregon,Tdaho,Washington,Much of New Mexico, and portions of Wyoming,Montana,and Colorado.also the Manifest Destiny and events connected to these two events like the treaty of Guadalupe Hidalgo, the Wilmot Provis and the Ostend Manifesto

Answer 2

James K. Polk achieved Manifest Destiny, ended the Texas-Mexico border conflict, and added the lands that would become the future U.S. states of Arizona, California, Nevada, New Mexico, and Utah. He settled the boundary in the Northwest with England, created the Department of the Interior, reduced tariffs, restored the Independent Treasury System, added two states to the Union, and appointed two Supreme Court Justices (all with 50% of the popular vote and a pledge to serve only one term, which he honored). Even if you oppose expansionism, it was an impressive record for a single term. He only lived for three months after leaving office.
