Zamboanga Sibugay
province of the Philippines
Zamboanga Sibugay, officially the Province of Zamboanga Sibugay (Cebuano: Lalawigan sa Zamboanga Sibugay; Filipino: Lalawigan ng Zamboanga Sibugay), is a province in the Philippines located in the Zamboanga Peninsula region in Mindanao. Its capital and largest town is Ipil and it borders Zamboanga del Norte to the north, Zamboanga del Sur to the east and Zamboanga City to the southwest. To the south lies Sibuguey Bay in the Moro Gulf.
Zamboanga Sibugay is the 79th province created in the Philippines, when its territories were carved out from the third district of Zamboanga del Sur in 2001.
History
The earliest recorded mention of Sibugay was in Historia de las islas de Mindanao, Jolo y sus adyacentes (1667) by the Spanish priest Francisco Combés, which describes the village of "Sibuguey" along the river Sibuguey.
Zamboanga Sibugay was formerly part of Zamboanga del Sur. Attempts to divide Zamboanga del Sur into two separate provinces date as far back as the 1960s. Several bills were filed in the Philippine Congress, but remained unacted.
It started in the 1960s when several bills were filed in Congress such as House Bill No. 17574 by the late Rep.
This brief starts where responsible research should: with the source description of “Zamboanga Sibugay” as province of the Philippines. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as province of the Philippines. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q13902. VIAF identifies the subject as 144450274. The Library of Congress control number is n2003122915. Authority coordinates are 7.800, 122.667. 3 of 6 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001 and 1667.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
