Compromise Sets Texas Boundaries

The Compromise of 1850 set Texas's boundaries at their present form. Texas ceded land which later became half of present day New Mexico, a third of Colorado, and small portions of Kansas, Oklahoma, and Wyoming to the federal government, in return for the assumption of $10 million of the old republic's debt. Post-war Texas grew rapidly as migrants poured into the cotton lands of the state.
