Through Partition (politics), World War II and Rice

The region was part of the now-defunct Southern Tagalog region until May 17, 2002. On May 23, 2005, Palawan and the highly urbanized city of Puerto Princesa were moved to the region of Western Visayas by Executive Order No. 429. However, on August 19, 2005, President Arroyo issued Administrative Order No. 129 to put in abeyance Executive Order No. 429 pending a review. On July 17, 2016, Republic Act No. 10879 officially designated the Southwestern Tagalog Region as Mimaropa, replacing the Region IV-B designation; however, no boundary changes were made. Nonetheless, the name continues to be used by other government agencies and the media.

Calapan is Mimaropa's regional center, while the highly urbanized city of Puerto Princesa is the most populous in the region. However, most regional government offices, such as the Department of Public Works and Highways and the Department of Budget and Management, are in Quezon City, Metro Manila, because Quezon City was the regional capital of Southern Tagalog.

History

Mimaropa, together with Calabarzon and Aurora was officially created with the partitioning of Southern Tagalog (Region IV) into the two regions on May 17, 2002, with the issuance of Executive Order No. 103 by then-President Gloria Macapagal Arroyo, for the purpose of promoting efficiency in the government, accelerating social and economic development, and improving public services in the provinces covered. Region IV-B was designated as Mimaropa, which stands for the island provinces belonging to the Southern Tagalog region—Mindoro (Oriental and Occidental), Marinduque, Romblon and Palawan. Region IV-A was designated as Calabarzon. Marinduque was a sub-province of Quezon, at that time known as Tayabas; it became an independent province in 1920. Quezon is now part of Calabarzon. Romblon was a subprovince of Capiz and was part of Western Visayas. When President Ferdinand Marcos enacted Presidential Decree No. 1, which organized the provinces into 11 regions as part of Marcos' Integrated Reorganization Plan, Romblon was transferred from Western Visayas to Southern Tagalog. Before World War II, Palawan was administratively grouped with Western Visayas.

On May 23, 2005, Executive Order 429 was issued, moving the province of Palawan to the region of Western Visayas, designating Region IV-B as "Mimaro". However, Palawan residents criticized the move, citing a lack of consultation, with most in Puerto Princesa and nearly all municipalities preferring to remain in Region IV-B. Consequently, Administrative Order No. 129 was issued on August 19, 2005, to address this backlash. This order directed the abeyance of Executive Order 429 pending the approval of an implementation plan for the orderly transfer of Palawan from Mimaropa to Region VI.

The 2010 Philippine Census of Population reported the region's name as "Mimaropa" and included Palawan as part of the region. As of 2014, it is unclear whether the transfer of Palawan to Western Visayas is still pending within the Philippine government. As of 2014, the National Statistical Coordinating Board of the Philippines continued to list Palawan province as part of the Mimaropa region.

On July 17, 2016, Republic Act No. 10879 formally established the Southwestern Tagalog Region to be known as the Mimaropa Region. This involved no boundary changes but was in effect merely a renaming and discontinuation of the "Region IV-B" designation.
