Step-by-step explanation:
The Organization for Black Agricultural Students Prior to 1965
The organization dedicated to black agricultural students prior to 1965 was the Colored Farmers' National Alliance. Founded in 1886 in response to the exclusionary practices of the larger Farmer's Alliance, the Colored Farmers' National Alliance quickly grew to encompass a large membership, claiming as many as a million members at its height. This organization represented the interests of black farmers who were often marginalized in the agricultural sector and participated in collective activities that had both economic and political implications, even though racial tensions of the era often complicated broader alliances within the farming community.
