In my personal opinion I think that if you live in Mexico and you have no idea about how to dance folklore or anything about diferent the customs, you have no idea about what your country is.
It is considered one cultural icon and the basic artistic expressions here in the country.
Here in Mexico the story tells that the dance existed already when the Spainiards came so they decided to take our dance but they mixed it with the Catholic religion and it creates this beautiful dance, best known as, Mexican Folklore. They took how they dance according to the power they had..
We can say that the customs also take the origin here because the “codices” (presidents or the biggest power in the country) tried to be seen as much as they can and when the people from Spain came learned about this and decided to taked, because they wear clothes according to the power they have.
As I already mentioned we have a lot of different type of dances and custumes according with the region or place you are. The most popular are “La Danza de los Viejitos” that came from the state of Michoacán.
Then we have the dance of our “jarochos” since this is the way we call people from Veracruz state.
Finally the one that represents us all and as I know the one that we imagine when other people said Mexican Folklore is “jarabe tapatio” from Guadalajara.
Our Folklore is really beautiful, and you have to learn more about … visit our country!
