Posted a day late.

December 6


African American delegates meet in Washington, D.C., to form the Colored National Labor Union as a branch of the all-white National Labor Union created three years earlier. Unlike the NLU, the CNLU welcomed members of all races. Isaac Myers was the CNLU's founding president; Frederick Douglas became president in 1872 - 1869

And this: December 6, 1869 - The Colored National Labor Union met in convention for the first time in Washington, D.C. Some 214 delegates attended. This union was a counterpart to the white National Labor Union. The assembly sent a petition to Congress requesting direct intervention in the alleviation of the "condition of the colored workers of the southern States" by subdividing the public lands of the South into forty-acre farms and providing low-interest loans to black farmers.
