Which country was not apart of the triple alliance

every single country existing by 1900 excluding Germany, Italy, and Austria-Hungary

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.

most people were factory or company owners.
