Final answer:
The National Council for Agricultural Education's beginning is not specified in the provided information, but historical agricultural organizations and educational efforts suggest the foundation of agricultural advocacy and education precedes it.
Step-by-step explanation:
The National Council for Agricultural Education does not have a clearly defined beginning date in the information provided. However, the information outlines significant agricultural organizations and educational efforts in the history of the United States, which were precursors to modern agricultural education and advocacy. Groups like the Patrons of Husbandry, popularly known as the Grange, started in 1867 and rapidly grew, emphasizing the cooperation among farmers for better shipping rates and prices on agricultural necessities.
The Farmers Alliance, emerging in the South and West, aimed to educate farmers about important issues and had nearly 4 million members at its peak. With the exclusion of certain demographics, the Colored Farmers' National Alliance was formed in 1886 and also saw rapid growth. These organizations and the continued development of agricultural education, such as the establishment of land-grant universities, would influence later formation of specific agricultural councils and education initiatives.
