Mexican president Porfirio Díaz and the revolutionary Francisco I. Madero signed the Treaty of Ciudad Juárez to end hostilities between each other's forces, concluding the initial phase of the Mexican Revolution.

José de la Cruz Porfirio Díaz Mori, commonly known as Porfirio Díaz, was a Mexican army general and politician who was the leader of Mexico from 1876, and the actual dictator after 1886 until his overthrow in 1911. Seizing power in a military coup, he served on three occasions as president of Mexico, a total of over thirty years, the longest of any Mexican ruler. This period is known as the Porfiriato and has been called a de facto dictatorship.
