Pre-Columbian era
The earliest known civilization is the Olmec. This civilization established the cultural blueprint by which all succeeding indigenous civilizations would follow in Mexico. Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near the coast in southeast Veracruz. The Olmec influence extended across Mexico, into Central America, and along the Gulf of Mexico. They transformed many peoples' thinking toward a new way of government, pyramid-temples, writing, astronomy, art, mathematics, economics, and religion. Their achievements paved the way for the Maya civilization and the civilizations in central Mexico.
Lašva Valley
The favorable geographical position of the Lašva Valley enabled the beginning of civilization along the Lašva River. However, due to the unprotected and open area numerous occupiers chose the mountainous regions to protect themselves. The earliest known remnants of civilized people were the Romans. Romans were adapt to the terrain and surrounding because of military might, which was of the utmost importance for survival.
