Hacienda Humboldt is an ejido in the municipality of Julimes (municipality), Chihuahua which was once a private cattle ranch. It belonged for a period of time to Luis Terrazas and was sold by him for the formation of a colony of South African refugees from the Anglo Boer War. The refugees were assisted in their project by President Theodore Roosevelt. He hired Marshall Latham Bond to represent him before Terrazas and the government of Mexico. The colony never particularly thrived. The Humboldt colonists already beginning in 1908 to emigrate to more active Mexican towns like Ciudad de Chihuahua and farming areas like the Mesilla Valley in the United States. Boers who stayed in Mexico married into local families, or moved away resulting in the loss of the community's identity with the Boers by the mid 1930s.
