History
Palawan holds some of the oldest evidence of people in the Philippines. The Tabon Caves on the west coast have yielded human remains tens of thousands of years old, and the Manunggul Jar, a burial jar with a boat of souls on its lid, is a national treasure. Mindoro may be the Ma-i of early Chinese records, and its Mangyan peoples developed their own scripts, traditionally incised on bamboo.
Spain claimed the islands from the late 16th century but held them loosely. Southern Palawan was long under the influence of the Sultanate of Sulu, and raiders from the south attacked Mindoro, Romblon and the Palawan coasts so often that forts and fortified churches such as those at Taytay and Cuyo were built to shelter townspeople. Puerto Princesa was founded as a naval station in 1872. Under the Americans, Culion became a leper colony from 1906 and Iwahig near Puerto Princesa an open prison farm, both still in existence in changed forms.
The Second World War left its marks. US aircraft sank Japanese ships in Coron Bay in September 1944, and in Puerto Princesa Japanese troops massacred more than a hundred American prisoners of war that December; the Allies then landed on Mindoro. Vietnamese refugees later settled in Palawan too. In recent decades the region has seen disputes over mining — the 1996 Marcopper spill on Marinduque's Boac River among the worst — and the 2023 oil spill off Oriental Mindoro, while the features the Philippines holds in the disputed Spratly Islands form Palawan's municipality of Kalayaan, all of them also claimed by some or all of China, Taiwan, Vietnam and Malaysia.
