History of Mexico Part I

Hello guys!
Well in this post I'm going to speak you about the Mexico's history, maybe if you read this you'll find new knowledges about this amazing country, and if you have a bad vision or a wrong idea now you can understand better some things. I'm sorry if this is long, but please you must understand are almost 2000 years of history, I'll summarize this, it is a promise, I don't wanna this seems boring for you. Let's start!
First of all you must know that the word "Mexico" has its origin in the "nahuatl" a native language of the centre of the country, and it means "Place in the moon"

The first culture in this country was in 1200 b.C and is called "Olmeca" that as the begin of the preclassic period (one of the three periods that the historians created for study the prehispanic that means before of the arrived of the spanish) and this was the first civilization in all America! They're know for their "Collosals heads" with 3.5 m. They were ubicated in Veracruz and Tabasco.

This is "La Venta" Tabasco

I think one of the most important cultures in Mexico was the "Maya" (in the Classic period, 800 b.C.) has anybody hear about it?
The Maya civilization is one of the most famous around the world, because they made many contributions in science, math, astronomy, architecture , etc. n They were ubicated in Yucatan, Quintana Roo, Campeche, and in parts of Guatemala
For example  did you know that they were the first who use the nuber "0"? Yes, they did. This civilization created the value "0". The mayas had a vigesimal (based in the 20) numeration.

This are the hieroglyph maya numeration 

The calendar was really important too, this counts the time in distincts aspects. (religious, ) they considered the begin of all on August 13th, 3114 b.C. 

And this calendar has periods, do you remember the end of the world the last December 21, 2012? Some persons thought the mayas said the world ended this day, but only was the begin of a new period.

For finish with this culture, have you ever seen to "Kukulcan" (Maya God) set down in "Chichen-Itzá" during a spring equinox? That is thankful to the maya's architecture, an optic illusion made for the sun toward the pyramid of Kukulcan. 

For finish with this post, I'll speak you the civilization that give us a symbol, important. "Azteca"

Azteca, Mexica or Tenochca (Post-Classic period 1325 a.D - 1527 a.D.) Were a population with big advences in war, farming, commerce, etc. Ubicated in Mexico's valley (Mexico city and State of Mexico)

They leaved "heron's place" in 1111 looking for a signal that their god "Huitzilopoztli" gave them for the founding of their own city. In 1321 they arrived to the Mexico's centre where after of fight versus the lord of "Azcapotzalco" they finally  saw the signal "An eagle over a nopal, eating a snake" (This will convert in our symbol, it's in our flag)

Then they built "Tenochtitlan" in this point; the big city, wich was destroyed by Spain during the colonization...

Well I hope you enjoy this fist part, I'll write the second part soon.
