The region's current name is in reference to its geographic position in the greater Visayas area.
History
Regions first came into existence on September 24, 1972, when the provinces of the Philippines were organized into 11 regions by Presidential Decree No. 1 as part of the Integrated Reorganization Plan by President Ferdinand Marcos. The provinces of Aklan, Antique, Capiz, Iloilo, and Negros Occidental were grouped together to form the Western Visayas region. The province of Palawan was transferred to Region VI on May 23, 2005 by Executive Order 429. The Department of the Interior and Local Government announced in June 2005 that the transfer had been completed. However, Palaweños criticized the move, citing a lack of consultation, with most residents in Puerto Princesa City and all municipalities but one preferring to stay with 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 Region IV-B to Region VI. Hence, Palawan is currently still part of Region IV-B. By virtue of Executive Order No. 183 issued on May 29, 2015, by President Benigno Aquino III, the province of Negros Occidental and its capital, Bacolod, were both removed from Western Visayas in order to form the Negros Island Region along with Negros Oriental. But later regained Negros Occidental and its capital, Bacolod City back into Western Visayas on August 9, 2017 when President Rodrigo Duterte dissolved the Negros Island Region, revoking Executive Order No. 183, s. 2015 through the signage of Executive Order No. 38, citing the reason of the lack of funds to fully establish the NIR according to Benjamin Diokno, the Secretary of Budget and Management.
