The call for a new convention began in 1896 soon after the General Assembly convened. Planners structured the referendum and election for delegates at the same time, and in such a way as to exclude the "wrong" voters. White registration fell from 164,000 to 74,000, and black registration fell from 130,000 to 13,000.
The convention began on February 8, 1898, at Tulane Hall (formerly known as the Mechanic's Institute). It's main purpose was to place the Democratic Party in firm control of the state. The delegates spent half of their time deciding the best way to disfranchise black voters. The rest of the time was spent writing the longest constitution to date. The convention ended on May 12, 1898.
