The Reform War, or War of Reform (), also known as the Three Years' War (), was a civil war in Mexico lasting from January 11, 1858 to January 11, 1861, fought between liberals and conservatives, over the promulgation of Constitution of 1857, which had been drafted and published under the presidency of Ignacio Comonfort. The constitution had codified a liberal program intended to limit the political, economic, and cultural power of the Catholic Church; separate church and state; reduce the power of the Mexican Army by elimination of the fuero; strengthen the secular state through public education; and economically develop the nation.Sinkin, The Mexican Reform, 169.
