Then came the 1845 annexation of Texas, where American immigrants to what was then Mexico’s state of Coahuila y Tejas had staged their slaveholder rebellion. The Texas Revolution’s martyrs included men like the slave trader James W. Fannin.
A few years later, the United States orchestrated the war with Mexico that led to one of the most colossal land grabs in American history: territory now including Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming.
This practice of remembering reminds us of the Americans whose ancestors never crossed the border with Mexico. It crossed them.
