The Emperor of Mexico was the head of state and ruler of Mexico on two non-consecutive occasions in the 19th century.
With the Mexican Declaration of Independence from Spain in 1821, Mexico became an independent monarchy—the First Mexican Empire (1822–1823). Mexico briefly reverted into a monarchy in the 1860s, during the Second Mexican Empire (1864–1867). In both instances of Empire, the reigning Emperor was forcibly deposed and then executed.
