Final answer:
The Southern Alliance did not welcome Black members, leading to the creation of the Colored Farmers' National Alliance by the Black Southerners.
Step-by-step explanation:

Black Southerners established their own organization, the Colored Farmers' National Alliance, in 1886 after being excluded from the Southern Alliance.

The exclusion was part of a broader context of segregation and racial discrimination during the era, where white and black populations often had separate organizations due to prevailing racial attitudes.
