The Jat historians tell us that Guti or Gutian is same as Jat. Jats when went to Mesopotamia, they became Jat to Guti due to linguistic reasons. Now let us find the history of Gutian people of Sumerian civilization.
History of Gutians
The Gutians were a people of ancient Mesopotamia who lived in the central Zagros Range. Nothing is still known about their origins. They may have been an Indo-European speaking people, possibly related linguistically to the Tocharians or to the modern Kurdish people.
The Gutian kings came to power in Mesopotamia circa the 22nd century BC (short chronology), more precisely around 2250 BC, by destabilising Akkad at the end of the reign of King Melem of Unug. The first Gutian king was Inkishuc. The last Gutian king was Tirigan, who was preceded by 21 kings, reigning roughly a total of one century. In the time of the Akkadian Empire, one prominent nomad tribe were the Guti, who lived in the Zagros Mountains.
Sumerian king Melem of Unug was defeated by the barbarian Gutians around 2250 BC. The Guti swept down, defeated the demoralized Akkadian army, took Agade and destroyed it about 2215 BC. The Empire became theirs.
From 2120 BC the Guti disappear from history
After a few kings, Gutian rulers quickly became more cultivated. They probably even strove to become more Akkadian than the Akkadians, since they had a nomadic ancestry to live down. Thus their rule ended by absorption, as it did for so many nomadic conquerors. Frequently though, such absorption isn't enough, the Guti lasted only about a century. At about 2120 BC, they were expelled from Mesopotamia by the rulers of Uruk and Ur when Utu-hejal of Uruk defeated gutian king Tirigan. From this point on the Guti disappear from history.
Legacy of Gutians
Most authorities credit the Sumerians with the invention of the wheel, initially in the form of the potter's wheel. The new concept quickly led to wheeled vehicles and mill wheels.
Jats worship Potter's wheel
Jats marriages start with the function of Chak Pooja, which means the worship of the potter's wheel. It is done in Jats of Rajasthan. I do not know about Jats in other states. I have been thinking about its logic but no body could explain it. I have tried to analyze our marriage customs and came to know that it tells step by step how they evolved and developed these traditions.
Now in the history of Gutians in Sumerian civilization above we find that the potter's wheel was invented by them and they made it a custom to remember it for generations to come. This still persists in Jats and it indicates the linkages between Jats and the Gutians of Sumer.
