Final answer:
The National FFA Alumni Association's establishment date is not provided, but the context relates to the history of agricultural organizations like the Colored Farmers' National Alliance, established in 1886 in response to exclusionary policies.
Step-by-step explanation:
The National FFA Alumni Association was not discussed in the provided information; however, this context is related to agricultural organizations and their histories. The provided information speaks about the Colored Farmers' National Alliance, which was created due to the exclusionary policies of the Farmer's Alliance. This alliance was formed by black farmers in Texas in 1886 in response to being excluded from the Farmers' Alliance. The Colored Farmers' National Alliance grew rapidly, boasting as many as a million members at its peak. Moreover, the movement related to the Farmers' Alliance was significant, encompassing various regional alliances and advocating for issues pertinent to farmers during the late 1800s.
The Farmers' Alliance itself was a significant force in the agriculture sector, reaching up to nearly 4 million members. However, by ignoring tenant farmers and African Americans, essential demographics in the farming community, the Alliance weakened its overall impact and unity.
