Answer 1

The U.S.-Mexican War began on April 25, 1846. It ended nearly two years later with the signing of the Treaty of Guadalupe Hidalgo, on February 2, 1848. Although the war was one of the most momentous conflicts of the nineteenth century, most Americans seem to know little about it today. Frequently, they confuse it with the Texas Revolution (1835-1836), the Spanish-American War (1898), or the border skirmishes with Mexican Revolutionaries that took place between 1913 and 1916. This situation is probably due in part to the overshadowing of the U.S.-Mexican War by the American Civil War, a much larger and more protracted conflict.

Since end of the U.S.-Mexican War, historians have been divided in their interpretations. Some have held the United States cupable. Others blame Mexico. Studies of the literature reveal the majority of writers have taken a balanced view, holding neither country entirely blameless. Despite the fact that there is no hard evidence to support their views, those who blame the U.S. claim that the war was a "shameless land-grab" brought on by the intrigues of President James K. Polk or that it was part of some sinister plot on the part of the so-called "Slavocracy" to extend slavery. These unfounded arguments are nothing new. They are the same ones used by nineteenth century Whig politicians in their attempts to discredit President Polk. The truth is more simple: The war was fought to defend the right of a free people, namely the citizens of the Republic of Texas, to determine their own destiny, that is to join the American union of states. This was a right that the government of Mexico sought to deny them.

Opposition to the war has often been exaggerated. Only a few outspoken Whig politicians, such as John Quincy Adams, were against it. At the time of the war another oft-cited critic, the writer Henry David Thoreau, was virtually unknown outside his hometown of Concord, Massachusetts. Most Americans enthusiastically supported the war. Approximately 75,000 men eagerly enlisted in volunteer regiments raised by the various states. Thousands more enlisted in the regular U.S. Army. There was no need for a draft. In some places, so many men flocked to recruiting stations that large numbers had to be turned away. Thousands of newly-arrived Irish and German immigrants also heeded the call to arms.

The initial battles of the war, Palo Alto and Resaca de la Palma, took place on Texas soil. Today, Palo Alto Battlefield National Historic Site, located near Brownsville, Texas, is the only U.S.-Mexican War battlefield in the U.S. National Parks system. All subsequent battles were fought in Mexico, California, and New Mexico.

The Treaty of Guadalupe Hidalgo, which ended the war, is still in force today. It not only fixed the Rio Grande as the boundary of Texas but required Mexico to cede to the U.S., in return for $15 million, all the territory that today includes the states of California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. Mexico sold this land as an indemnity for the cost of waging a war the U.S. had not sought and because it had no money with which to pay either the indemnity or the millions of dollars in debts that it had owed to private U.S. citizens for years.The U.S. also agreed to assume responsibility for those debts. Oftentimes, historians fail to point out that Mexico exercised very little actual control over the ceded territory and that it contained less than 1% of the country's population. And at the time, no one knew about the gold and other minerals that would later be found there.
