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.
History of Kutch
The earliest human settlements can be traced back to the Early Harappan Period of Indus valley civilization, c. 3300–2600 BCE. Several sites belonging to this civilization are discovered in Kutch. Dholavira, locally known as Kotada Timba, is one of the largest and most prominent archaeological sites in India belonging to the civilization. It is located on the Khadir island in the northern part of the Kutch. The island is surrounded by water in the monsoon season. The Dholavira site is believed to have been inhabited between 2900 BCE and 1900 BCE, declining slowly after about 2100 BCE, briefly abandoned and then reoccupied, finally by villagers among its ruins, until about 1450. Other sites include Surkotada, Desalpar Gunthli, Pabumath, Kanmer and Shikarpur. More than 60 major Harappan sites are discovered around the Rann of Kutch.
