 The Sultanate of Sulu enjoyed peaceful ties with the Hindu Sultanate of Java.As a token of appreciation, the rulers of Java sent their elephants to Sulu, much as they had sent Javan elephants to the Sultanate of Maguindanao, which also partly gives the reason why skeletal remains of small elephants are found in Mindanao, south Philippines.The Sultan of Sulu and his family shipped some of their prized Javan elephants to northeast Borneo due to lack of land and for the elephants to help in hauling logs out of the forest to create fast and long ship vessels.
