Mexican American War 1846-1848

Mexican American War Timeline

Cause and Effect of Texas Independence

          This timeline is a road map of a one way street. There are no off ramps, but numerous temporary stops that begin “deep in the heart of Texas” and end in the deep blue Pacific. The fuel for this trip was the belief that providence had designed the fate of the American nation called “Manifest Destiny”. This political philosophy preached that the United States had the God given right to expand America's borders from sea to sea.

After your review of this timeline, we call your attention to the additional links located below this table detailing the decisive elements of this war.

1821 Mexico revolts against Spanish rule Mexican independence; gained south western territories from Texas to California
1822-1824 Mexico encourages Americans to settle Texas and particularly areas subject to Comanche Indian attacks to provide a defense for Mexican settlers. Americans, attracted by cheap land, many with their slaves, settled large areas of Texas. Immigrants were required to swear oath of allegiance to Mexico and to follow the State religion. The latter requirement was more honored in the breach. Stephen F. Austin establishes a colonial judicial system.

Every American war was defined and illuminated by thousands of moving parts. In a sense, a war machine is like a huge wheel designed to advance a strategy, a goal, but inherently capable of sudden stops and reversals. You may examine the wheel and its component spokes (links) that propelled the American war machine, all trans-formative, and the human hands that created the turns and pivots that marked this war and our times.
