Following the disappointing results of that election, the Wheel merged with the Northern Farmer's Alliance in an attempt to combine both organizations' political clout. However, the coalition featured two factions who had the same problems but fundamentally disagreed on how to solve them: one of anti-tariff Southern Democrats and another of Northern farmers who were traditionally Republican and supported tariffs. The group became the Populists in 1890. During the late 1880s and 1890s, the Democrats worked to consolidate their power and prevent alliances among African Americans and poor whites in the years of agricultural depression. They were facing competition from the new Populist and other third parties. In 1891, state legislators passed a statute requiring a literacy test for voter registration, when more than 25% of the population could not read or write. In 1892 the state passed a constitutional amendment that imposed a poll tax and associated residency requirements for voting, which combined barriers sharply reduced the numbers of blacks and poor whites on the voter rolls, and voter participation dropped sharply.
