Why did the mongols have so much success in their military conquering campaign?

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.

there were 6 major base camps.   the base camps were located in alva, fort reno, fort sill, the madill provisional internment camp headquarters, mcalester and camp gruber.
