The plan nullified the Constitution while it continued to recognize the election of moderate liberal Ignacio Comonfort as President.
Conservatives had fiercely objected to the Constitution of 1857, which abolished special privileges (fueros) of the Catholic Church and the Mexican Army.
President Ignacio Comonfort had not been a strong supporter of the Constitution and joined with Zuloaga, commander of the garrison in Mexico City.
Three months after some Mexican states accepted the Plan, the executive called a special session of Congress whose sole mission was to draft a new constitution.
Comonfort hoped that "by assuming dictatorial powers he could hold the extremists on both sides in check and pursue a middle course."
