One of the first mentions of Buru occurred in the Nagarakretagama - an Old Javanese eulogy to Hayam Wuruk, the ruler of the Majapahit Kingdom, dating back to 1365 [REF].
In the 16th-17th centuries Buru was claimed by the rulers of Ternate island and by the Portuguese; both claims were, however, symbolic, as neither party controlled the island, but only visited it on trade matters.
