The Bourbon Triumvirate refers to three prominent Georgian politicians during the late 1800s. The three members (Joseph E. Brown, Alfred H. Colquitt and John B. Gordon) held complete control over the government from 1872 to 1890.
These politicians were particularly interested in the railroad and coal-mining businesses. They also championed white supremacy, low taxes with a frugal state government and cheap labor on farms and factories.
The 13th Amendment is to abolish (rid) slavery. I'm not understanding the question as to what the purpose was. Can you be more specific or did you just need to know what it was?
