David Walkers Appeal was written about 180 years ago and the tradition is as old as slavery.
The ideas of Black Liberation also has their origin in the slave rebellions of the Maroons (escaped slaves) in the Caribbean against the British and of people such as Nate Turner and John Brown, who led slave rebellions in the United States.
Are we MEN! ! — I ask you, 0 my brethren I are we MEN? Did our Creator make us to be slaves to dust and ashes like ourselves? Are they not dying worms as well as we? Have they not to make their appearance before the tribunal of Heaven, to answer for the deeds done in the body, as well as we? Have we any other Master but Jesus Christ alone? Is he not their Master as well as ours? — What right then, have we to obey and call any other Master, but Himself? How we could be so submissive to a gang of men, whom we cannot tell whether they are as good as ourselves or not, I never could conceive. However, this is shut up with the Lord, and we cannot precisely tell — but I declare, we judge men by their works.
A couple of quotes from David Walker’s Appeal:
The whites have always been an unjust, jealous, unmerciful, avaricious and blood-thirsty set of beings, always seeking after power and authority.
…to my no ordinary astonishment, [a] Reverend gentleman got up and told us (coloured people) that slaves must be obedient to their masters — must do their duty to their masters or be whipped — the whip was made for the backs of fools, &c. Here I pause for a moment, to give the world time to consider what was my surprise, to hear such preaching from a minister of my Master, whose very gospel is that of peace and not of blood and whips, as this pretended preacher tried to make us believe. What the American preachers can think of us, I aver this day before my God, I have never been able to define. They have newspapers and monthly periodicals, which they receive in continual succession, but on the pages of which, you will scarcely ever find a paragraph respecting slavery, which is ten thousand times more injurious to this country than all the other evils put together; and which will be the final overthrow of its government, unless something is very speedily done; for their cup is nearly full.-Perhaps they will laugh at or make light of this; but I tell you Americans! that unless you speedily alter your course, you and your Country are gone! ! ! ! !
Black Nationalism and Black Liberation Theology generally have a doctrine that the black race has a divine mission to destroy white America and the traditional church.
