Simón Bolívar was motivated by the ideals of "liberty, equality, and fraternity" from the French Revolution. He fought against colonial rule and tried to win freedom and reforms for his people. Agustín de Iturbide was motivated by fear of reforms and personal ambition. In Spain at the time, liberals had forced the king to issue a constitution. Iturbide feared that the new Spanish government might force reforms on the colonies as well. To counter this threat, he stopped fighting Mexican revolutionaries and instead led them in overthrowing Spanish rule. However, instead of freedom, the Mexican people gained a new monarch when Iturbide declared himself emperor.
