Adityawarman agreed, with one condition if the Minangnese got defeated, He can take the whole Pagaruyung Kingdom area. Aditya brought out his strong and big female buffalo. It seemed the buffalo was wild enough, went amock in the middle arena. While the Minangnese just brought out a very little buffalo. When the little buffalo entered the arena he thought the big buffalo was his mother. So he run to get closer and got milk from the female buffalo's nipple. Suddenly the big buffalo fell down to the ground, and died. Actually the Minangnese put a pair of sharp metal at the edge of the little buffalo's horns. So when he came closer, the big female buffalo killed. The Minangnese won the contest, they shouted "MINANG" which means "WIN". Since then they named their ethnic group as MINANGKABAU or "The winning buffalo".
