Oriental Mindoro: History
=== Japanese occupation ===
A Japanese force landed on northeastern Mindoro in the Philippine Islands on 27 February 1942.
Almost three years later, after the invasion of Mindoro by Allied forces, they proceeded to land to Bongabong and heading to and capturing Calapan, the capital of the united Mindoro Province at the time on 24 January 1945.
==== Foundation ====
After World War II, reconstruction and rehabilitation of infrastructure and the economy took place on the island, which then constituted a single province. This was partitioned on 13 June 1950 into Oriental Mindoro and Occidental Mindoro by virtue of Republic Act No. 505.
In the decades after the War, Mindoro attracted settlers from overpopulated provinces in the Philippines. Apart from the hope to become landowners or to have better tenancy conditions, the Hukbalahap Rebellion in Central Luzon was an important factor for migration. Under the settlement program of the National Resettlement and Rehabilitation Administration (NARRA) founded in 1954, families from Central Luzon were settled in the Bongabong-Pinamalayan area. This project ended in 1956 after 606 families (3,636 people) were settled on 8,600 hectares (21,000 acres) of public land. Since then, new settlers have continued to migrate to Mindoro until today.
On November 15, 1994, a magnitude 7.1 earthquake struck the Verde Island Passage located north of Oriental Mindoro, killing 69 people in the province, with most casualties due to the tsunami caused by the earthquake. Within a year after the calamity, however, the provincial government under Governor Rodolfo G. Valencia was able to successfully rehabilitate the province in a brisk manner, and was thus conferred the Disaster Management Award by the National Disaster Coordinating Council in July 1995.
The island currently sees an ongoing conflict between the Armed Forces of the Philippines and insurgents. On March 6, 2010, eleven soldiers were killed and seven were hurt in a gun battle with the New People's Army in Mansalay, Oriental Mindoro.
