15 years: from 1821 until 1836.
24 years: from 1821 until 1845
With an area of 1,964,375 km2 vs. 505,992 km2, almost 4 countries the size of Spain would fit inside Mexico. On a more "international scale," Mexico is roughly the same size as Spain, the United Kingdom, France, Italy, and Germany all put together.
Mexico declared its Independece in 1810. Spain recognized that Indepence in 1821. Texas declared its Independence in 1836. Texas was a Republic for nine years before becoming a state in 1845.
Eleven years and twelve days: from September 15, 1810 to September 27, 1821.
The Spanish Empire qualifies as such. Mexico (or New Spain, as it was called at the time) was ruled by a viceroy, appointed by the Spanish King. The last viceroy was Juan O'Donoju (1762 - 1821).
Mexico declared its independence first, on September 16, 1810. It was on September 18, 1810, when Chileans elected a local democratic government for the first time (Chile's National Day). However, the ties with Spain remained and Chile declared its independence from Spain almost eight years later (February 12, 1818)
Only Spain did that (1521 - 1821)
Never. Both Mexico and the territory of New Mexico were conquered and/or settled by the Spanish Empire, since Mexico was "discovered" by Hernan Cortes in 1519. Mexico became an overseas territory of the Spanish Empire from 1521 until the end of Mexico's War of Independence (1810-1821) against Spain.
About 200 years (modern nation of Mexico, that is).
