The Stonewall area was originally part of the Maxwell Land Grant awarded by the government of New Mexico to two Mexican citizens in 1841. The grant area was later owned by foreign investors who created the Maxwell Land Grant Company and attempted to expel the farmers, ranchers, and miners, both Anglos and Hispanics, who had settled on lands in the grant. The Stonewall incident in 1888 was the most violent of many incidents in the dispute between the Maxwell Company and the settlers on grant lands. The company had sold of grant land in Colorado to a group of investors including Colorado governor, Alva Adams. The investors intended to develop the land for tourism and sought the immediate eviction of the settlers. A large group of settlers, mostly Hispanics, gathered to protest and surrounded a hotel in Stonewall where the company's employees barricaded themselves. A gunfight ensued in which three of the protesters were shot and killed. In the aftermath several of the protesters were arrested and later convicted of inciting a riot.[4]
The Supreme Court of the United States affirmed the ownership of the grant land by the foreign investors and by 1899 most of the original settlers had either been evicted or had come to terms with the company.
