Explanation:

feudalism is basically the way of using land for power. the more land you have the more power you have. the king gives the lords land in exchange for protection. the lords give vassals land in exchange for an army, vassals let peasants work on their land for a living and etc... so the more land you have the higher you are in the hierarchy

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.
