Ignacio José de Allende y Unzaga, commonly known as Ignacio Allende, was a captain of the Spanish Army in New Spain who came to sympathize with the Mexican independence movement. He attended the secret meetings organized by Josefa Ortiz de Domínguez, where the possibility of an independent Mexico was discussed. He fought along with Miguel Hidalgo y Costilla in the first stage of the struggle, eventually succeeding him in leadership of the rebellion. Allende was captured by Spanish colonial authorities while he was in Coahuila and executed for treason in Chihuahua.

The Mexican War of Independence was an armed conflict and political process resulting in Mexico's independence from the Spanish Empire. It was not a single, coherent event, but local and regional struggles that occurred within the same period, and can be considered a revolutionary civil war. It culminated with the drafting of the Declaration of Independence of the Mexican Empire in Mexico City on September 28, 1821, following the collapse of royal government and the military triumph of forces for independence.
