There sprang up rivalries and jealousies. Yudhishthira, the eldest of Pandu brothers, was senior in age to Duryodhana, therefore when Dhritarashtra thought of making him his heir-apparent, Duryodhana strongly remonstrated against this proposal. After that the animosity between the Kauravas and Pandavas increased to such an extent that there were several plots to exterminate the Pandavas. The Pandavas had to face great odds. Duryodhana invited them to a gambling match, in which with the help of his maternal uncle Shakuni, he won from Yudhishthira everything, his brothers, his own freedom and even his wife Draupadi.
Duryodhana exultingly sent for Draupadi and when she refused to come, she was dragged by the hair of her head by Duhsasana. Duryodhana insulted her by asking her to sit upon his thighs. At this juncture Bhima vowed to break the thighs of Duryodhana for this offence and ultimately in the great war of Mahabharata, he fulfilled his vow. On the eighteenth day of the war, when Kauravas were badly defeated and all the brothers except Duryodhana were slain, Duryodhana hid himself in a lake. He was discovered and brought out with taunts.
Ultimately in the dual that followed, he was killed by Bhima, with his mace. Both Duryodhana and Bhima had learnt the use of mace under the tutorship of Balarama, the elder brother of Krishna. In the war Kristina sided with Pandavas and his army with Kauravas. See : Daropadi (Draupadi) and Krishna
