Final answer:
The Farm Holiday Association led by Milo Reno was the movement in the eighteenth and nineteenth centuries that engaged in violent protests and criminalized farmers as they sought government intervention in setting farm produce prices.
Step-by-step explanation:
During the eighteenth and nineteenth centuries, the movement that criminalized farmers, often resulting in violent protests, was known as the Farm Holiday Association. This organization, led by Milo Reno, gained notoriety particularly in the Midwest states, including Iowa, Nebraska, Wisconsin, Minnesota, and the Dakotas. Their tactics included farm holidays where no produce would be sold or purchased until government demands were met, barricading roads, destroying produce, and engaging in 'penny auctions' where they would bid minimal amounts on foreclosed farms and threaten competition, subsequently returning the land to its original owners. Such protests escalated to the extent of threatening judges and causing at least one death.
