Emperor of Mexico Wikipedia
The Emperor of Mexico (Spanish: Emperador de México) was the head of state and ruler of Mexico on two non-consecutive occasions in the 19th century.
With the Declaration of Independence of the Mexican Empire from Spain in 1821, Mexico became an independent monarchy—the First Mexican Empire (1822–1823). The monarchy was soon replaced by the First Republic of Mexico. 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.
