Answer:
White supremacist paramilitary organizations, allied with Southern Democrats, used intimidation, violence, and assassinations to repress blacks and prevent them from exercising their civil rights in elections from 1868 until the mid-1870s. The insurgent Ku Klux Klan (KKK) was formed in 1865 in Tennessee (as a backlash to defeat in the war) and quickly became a powerful secret vigilante group, with chapters across the South. The Klan initiated a campaign of intimidation directed against blacks and sympathetic whites. Their violence included vandalism and destruction of property, physical attacks and assassinations, and lynchings. Teachers who came from the North to teach freedmen were sometimes attacked or intimidated as well.

Why 1807 significant
The members of the Society for the Abolition of the Slave Trade decided to concentrate on a campaign to persuade Parliament to prohibit the trading in slaves, for tactical reasons. They felt they were more likely to succeed, than if they demanded the abolition of slavery itself throughout the empire.
Why 1833 significant
The British Parliament passes the Slavery Abolition Act 1833, ultimately giving slaves in much of the British Empire their freedom (enacted 1834).
