The basic sources of Krishna's stories are the epics, Mahabharata, and Bhagvat Puran. There came a time when mother earth was unable to bear the sins and cruelty committed by evil kings and Rulers mother earth then prayed to Lord Brahma, the creator of the universe to relieve her from the sinful kings.

Brahma prayed to the supreme Lord Vishnu for his reincarnation and to relieve earth from those evil rulers. Kansa the ruler of Mathura was one such evil king. He had a sister named Devaki who was married to Vasudeva. The day Devaki and Vasudeva got married a voice from the sky, forecasted that Devaki’s eighth son will bring an end to Kansas rule and will kill him. A frightened Kansa held the couple captive.
He then vowed that he will kill every child of Devaki and Vasudeva, seeing their first seven children being killed by the cruel Kansa.

In a subconscious state of mind, he took the baby away from the prison and placed him in a safer place. Vasudev reached a house in Gokul exchanged Lord Krishna, with a newborn girl of Nanda and Yashoda, and returned to prison with a girl child.
As soon as Kansa came to know about the newborn, he again tried to kill the child, the infant ascends to heaven and transforms itself into the goddess Yogamaya and said: “O foolish Kansa what will you get by killing me? Your killer is already born”. Meanwhile, Krishna was raised as a cowherd in Gokul. The childhood of Lord Krishna is filled with stories of his mischievous pranks and incidents that depict his divine nature.

Amongst the prisoners were 16,000 women whom Narakasura had captured, knowing that the society would not accept women who had been held captive by a demon for years, Krishna married the sixteen thousand women making them all their wives, and giving them a respectable place in the society.
6. Shri Krishna Stood by Pandavas

Still, he agreed to be present on one side of the army to avoid any kind of war between the cousins Krishna requested Kauravas to give a small amount of land to the Pandavas. Then Duryodhana, however, opposed any compromise. Krishna gave his dearest friend Arjuna a choice. Once the war became inevitable, either he could choose Krishna himself or he could choose the armies of Krishna. Arjuna preferred Shri Krishna’s presence instead of his troops, while Duryodhana chose the Narayani Sena or the army of Krishna.

8. Gandhari Cursed Shri Krishna to Die
Sri Krishna represents all of the human and spiritual elements. He played a human role as an avatar, but at the same time, he was a fully realized spirit. Krishna met Gandhari after the battle of Kurukshetra was over to give her condolences as the Pandavas had won the battle and Gandhari had lost her hundred sons to death. Gandhari in her rage aggressively came up to Lord Krishna and poured her anger on him. According to her, the mass killing and the war could have been avoided by Krishna, but he did not.
Her grief turned into vengeance and she cursed Krishna that if her devotion towards shiva was pure and if she was true to her husband, all her life, then 36 years from that day, Krishna would die. His kingdom Dwarka would be flooded and the entire clan of Sri Krishna will be destroyed. In the same way, he made the Kauravas reach death. 36 years later, Gandhari's curse came true, Dwarka was consumed by the Arabian sea, the Yadav race went extinct, and Lord Krishna and Balaram had left the mortal world. Kali-yuga had arrived. The Pandavas felt that there was no purpose left for their existence.
