If you mean after the Mexican War of Independence (1810-1821), it owned the whole states of California, Nevada, Utah, Arizona, New Mexico and Texas, as well as parts of Wyoming, Colorado, Oklahoma and Kansas.
If you mean after the Mexican Revolution (1910-1921), it had the same territorial area as it has now.
Mexico was busy with its own Mexican Revolution so it couldn't 'properly' respond.
the United states paid Mexico $15 million dollars for this land, which became known as the mexican cession
yes it is because America captures Mexico but now it's a own land!
Francisco Maders, a wealthy rancher, called for a revolution to defeat Diaz. Leaders arose in different parts of Mexico and gathered their own armies.
During which revolution? During the American revolution? Yes, it was the most successful colony of Spain at the time. During the Mexican revolution? Maybe, it was a country on the beginnings of it own industrialization.
No. Only if you are son of a Mexican.
Yes! Mexico own this land.
Yes.
I guess you mean during their independence war. No, they fought their war on their own, without outside interference. --- In the early days of the Mexican Revolution (ca1910-ca1930), some foreigners came in from Los Angeles to help the Flores Maglón brothers and their Partido Liberal Mexicano. There were European and U.S. financial backers to the Conservative groups. Mostly, though, the Mexican Revolution was a civil war.
One of the wars, was the Mexican-American war where Mexicans and Americans fought over where the border was located. Another war was between Texas and Mexico which was the Texas Revolution, which Santa Anna was in charge of. Texas won and became free from Mexico. A third Mexican war was between the Mexicans and Spain. America intervened on this war in order to help Mexico gain their independence (For their own personal gain). Mexican defeat of the French is celebrated on the 5th of May, or, Cinco de Mayo.
In fact, Mexico invented such sign ('$') for the Mexican peso and the US took it for its own currency.
They were fighting on their own land for their own cause.
