Central and East Java, the areas where the ethnic Javanese lived, was still claimed by the Hindu-Buddhist king living in the interior of east java at Daha. The coastal areas such as Surabaya were, however, Islamised and were often at war with the interior, except for Tuban, which remained loyal to the Hindu-Buddhist king. Some of the coastal Muslim lords were converted Javanese, or Muslim Chinese, Indians, Arabs, and Malays who had settled and established their trading state on the coast.
