Bulgaria and Romania side by side: 43 shared sourced indicators across 9 domains, and the 4 events their chronicles record of each other.

Canonical: https://terralore.co/compare/bgr-vs-rou
Updated: 2026-08-10 (latest of the two dossiers' refreshes and the two chronicles' verification dates)

Two sourced records set beside each other — nothing on this page was written for the pair. Every figure is the same observation, with the same source, as on the two national dossiers; every event is the same record, with the same sources, as on its own chronicle. Figures are compared, never graded. A "—" is an absence in the source data, never a zero; each value shows its own observation year — vintages differ by indicator and nation.

## Formation

- Bulgaria: 681 — Byzantium acknowledges Bulgaria as an independent state

- 7 Sep 1940: **Treaty of Craiova returns Southern Dobruja** — By the Treaty of Craiova, Romania ceded Southern Dobruja back to Bulgaria, restoring the 1912 frontier, the one Axis-era border change that was not reversed after the Second World War.
