 They defined the boundaries of the 7th district, which was called the "shoestring district" because of its long, narrow shape that included many black precincts.In 1892 and 1894 the majority-black voters of the district elected George W. Murray to Congress; he was the only African American to serve in Congress in those sessions and, following disfranchisement and demographic changes, the last elected from the state until Jim Clyburn in 1992.In 1895, the Democrat-dominated state legislature passed a new constitution, disfranchising black voters by changes to voter registration and electoral rules that were applied against them in a discriminatory way.
