Joseph Marro was a member of the Continentalist Party from Mexico del Norte who was elected to the Mexican Senate in 1845. Marro was a supporter of the war against the Confederation of North America. When former President Miguel Huddleston called for a cease-fire in the war and negotiations with the C.N.A., Marro denounced him as "a traitor, pure and simple."
In his memoirs, In the Service of Mexico, published in Mexico City in 1871, Marro wrote of the 1851 Mexican elections, "We did not vote for a man who would lead us to greater glory, or for a man who could inspire Mexico with dreams and visions. Nor did we have the choice between reasonable programs, for none were set forth by Niles or Blaine. But the people were tired of war, and this decided the contest."
Sobel's sources for the political career of Joseph Marro are Marro's memoirs and Philip Wright's The Marroista Interlude: The Decline of Liberty in Mexico (Mexico City, 1952).
