History
In 1849 a group of Seminoles migrated from Indian Territory to Mexico to establish a military colony. Led by Wild Cat, a noted Seminole chief, and John Horse (Gopher John), the leader of the Black Seminoles, the group consisted of about one hundred Seminoles and one hundred Black Seminoles. About five hundred Kickapoos from Missouri joined Wild Cat's group on the Rio Grande at Eagle Pass. In July, 1850, the group was admitted to Mexico. Wild Cat, representing the entire group, was assigned approximately 70000 acre, half at the headwaters of the Rio San Rodrigo and half at the headwaters of the Rio San Antonio. The citizens of Remolino, nearby, were not pleased and complained to the provisional government in Coahuila, which issued a decree saying that other lands would be found upon which the Indians could be settled. Nevertheless, some of the Indians did eventually settle near Remolino.
