wow, that's since:
In the spring of 1879, thousands of colored people, unable longer to endure the intolerable hardships, injustice, and suffering inflicted upon them by a class of Democrats in the South, had, in utter despair, fled panic-stricken from their homes and sought protection among strangers in a strange land. Homeless, penniless, and in rags, these poor people were thronging the wharves of Saint Louis, crowding the steamers on the Mississippi River, and in pitiable destitution throwing themselves upon the charity of Kansas. Thousands more were congregating along the banks of the Mississippi River, hailing the passing steamers, and imploring them for a passage to the land of freedom, where the rights of citizens are respected and honest toil rewarded by honest compensation. The newspapers were filled with accounts of their destitution, and the very air was burdened with the cry of distress from a class of American citizens flying from persecutions which they could no longer endure.1
