History
Under Nguyễn lords
In 1698, Lord Minh ordered Lễ Thành hầu establishing Gia Định prefecture with two districts in Cao Miên territory: Phúc Long district based on Đồng Nai, protected by Trấn Biên palace; and Tân Bình district based on Sài Gòn, protected by Phiên Trấn palace.
In 1715, Phiên Trấn commander – Trần Thượng Xuyên, and Trấn Biên deputy commander – Nguyễn Cửu Phú led Gia Định forces to support Nặc Yêm (Ang Em) in defeating Nặc Thâm (Ang Tham) and retaking the La Bích (Lavek) citadel. Lord Minh appointed Nặc Yêm as the new king of Cao Miên.
Under Nguyễn dynasty
Biên Hòa province was first established in 1832 when Emperor Minh Mạng divided Lower Cochinchina into Six Provinces. Biên Hòa province contained one prefecture: Phước Long, divided into four districts: Phước Chính, Phước An, Bình An, and Long Thành.
By the 4th year under Tự Đức (1851), Biên Hòa contained two prefectures: Phước Long, and Phước Tuy, dividing to seven districts: Phước Chính, Bình An, Phước Bình, Nghĩa An, Phước An, Long Thành, and Long Khánh.

Begin with the source’s own compact description: “Biên Hòa province” is former province under the Nguyễn dynasty and the Republic of Vietnam. The dossier treats that line as a proposition to test through Biên, province and former, not as a finished interpretation.
Why this record matters
The phrase “former province under the Nguyễn dynasty and the Republic of Vietnam” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Aug 27, 2026. The linked authority identifier is Q2502014. Authority coordinates are 10.950, 106.874. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2025, 1698, 1715 and 1832.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
