Theodore Holmes (1890 - ?) was a Mexican historian in the early twentieth century who specialized in the history of Negro slavery in both the U.S.M. and the Southern Confederation of the Confederation of North America.
In the wake of the Chapultepec Incident of 4 January 1916, Holmes was appointed to the head of a subcommittee studying the history of slavery in Mexico. In 1917 he produced as essay called "The Rainbow Nation" which was widely quoted, and became the basic document for future studies of race relations in the U.S.M. The essay was eventually published in Mexico City in 1925 as part of a collection edited by Holmes called The Rainbow Nation and Other Papers. Sobel quotes a long excerpt from "The Rainbow Nation" in which Holmes suggests allowing Mexico's slaves to emigrate to the C.N.A. Consalus, however, rejected Holmes' suggestion, although he was unable to come up with any alternative.
Holmes may have emigrated later in life to the C.N.A. In 1945 he published a book in New York City called Slave Rebellions of the 1820s about slave uprisings in the Southern Confederation during the Era of Harmonious Relations. Sobel cites Holmes when discussing Howard's Rebellion, the Levering Conspiracy, and the Insurrection of 1829.
Both of Holmes' books appear in Sobel's bibliography.
