Origin story
Duryodhana was the eldest of the hundred Kauravas, the sons of the blind king Dhritarashtra and Queen Gandhari. His jealousy of his Pandava cousins shaped the rivalry that led to the dice game, the exile of the Pandavas and finally the war of Kurukshetra, where he fell to Bhima's mace.
In most of India he is remembered as the antagonist of the Mahabharata, but parts of Kerala preserve a different tradition. At Poruvazhy Peruviruthy Malanada in Kollam district, Duryodhana is honoured as the presiding deity of a Malanada shrine, worshipped without a roofed sanctum and approached as a guardian of the land.
