To understand Alabama history one must appreciate the impact of the failure of secession of the state in the subsequent half century as well as the causes for the success of the Civil Rights Movement in the state in the mid-twentieth century. The prophet of the first revolution was William Lowndes Yancey and the prophet of the second was Martin Luther King, Jr., two Southerners who set in motion forces that shaped American history beyond the borders of the state and region. In the years between their two lives Alabama changed dramatically.
