Which organization of farmers is known for its influence on the current Texas constitution?

The Grange, also known as the Patrons of Husbandry, is recognized for its significant influence on the current Texas constitution. Founded in the post-Civil War era, the Grange was established to advocate for farmers' rights and address the economic issues faced by agricultural workers. This organization played a vital role in pushing for reforms that emphasized the needs and interests of farmers, particularly in response to issues like railroad monopolies and unfair pricing practices.

Their activism contributed to the demand for legislative changes that ultimately shaped the Texas constitution, particularly during the late 19th century when the state sought to address the grievances of agrarian communities. The Grange helped inspire the Constitution of 1876, which included provisions aimed at limiting the power of railroads and promoting agrarian interests, showcasing the impact of this organization on Texas governance and policy making.

This rich history of advocacy illustrates the Grange's crucial role in influencing not only the constitution but also the broader agricultural policies that would benefit Texas farmers for generations. The other organizations listed, while also significant in various contexts, did not have the same foundational influence on the rewriting of the Texas constitution as the Grange did.
