Following a brief coalition between the Republican Party and Populists in the late 19th century, the South Carolina legislature followed others in the South in passing a constitution to disenfranchise most blacks and many poor whites. The Constitution of 1895 was a departure from the Reconstruction Constitution of 1868 that aimed to keep the majority black population from voting. However, the poll tax, property requirements and literacy requirements also keep poor whites from voting. By excluding blacks from politics, the Democrats secured their power and ended the Republican challenge. The legislatures passed such laws and constitutions from 1890 to 1908, turning most of the South into a one-party region dominated by Democrats. The Solid South disenfranchised large portions of its states' populations. The exclusion of freedmen and their descendants from the political system resulted in the South Carolina Republican Party with very little influence within the state for generations after. This control would last until the second half of the twentieth century.
