A rapid pace of change across the country, especially in growing cities, combined with new waves of immigration and migration of rural whites and blacks to cities, all contributed to a volatile social environment and the rise of a second Ku Klux Klan (KKK) in the South and Midwest after 1915. In many areas it represented itself as a fraternal group to give aid to a community. Feldman (1999) has shown that the second KKK was not a mere hate group; it showed a genuine desire for political and social reform on behalf of poor whites. For example, Alabama Klansmen such as Hugo Black were among the foremost advocates of better public schools, effective Prohibition enforcement, expanded road construction, and other "progressive" measures to benefit poor whites. By 1925, the Klan was a powerful political force in the state, as urban politicians such as J. Thomas Heflin, David Bibb Graves, and Hugo Black manipulated the KKK membership against the power of the "Big Mule" industrialists and especially the Black Belt planters who had long dominated the state.
