Coșei
river in Romania
The Coșei is a right tributary of the river Maja in northwestern Romania. It flows through Sălaj County and Satu Mare County in the historical region of Crișana, draining a hilly area of the Someș Plateau. Its length is 16 km (9.9 mi) and its basin size is 97 km2 (37 sq mi).
The Coșei is part of the Danube river system: it flows into the Maja, which is a right tributary of the Crasna. The Crasna in turn is a left tributary of the Tisza in Hungary, which ultimately discharges into the Danube.
Geography
The Coșei originates near the village of Coșeiu (Hungarian: Kusaly) in southern Sălaj County. From its source the river flows generally northward through the hilly terrain of the Someș Plateau, the northern subdivision of the Transylvanian Plateau. The landscape is characterised by rolling hills with elevations of 300–500 metres, dissected by a network of valleys and small watercourses typical of the plateau region.
The river passes through or near the village of Archid in Coșeiu commune, then crosses the border between Sălaj and Satu Mare counties near Nadișu Hododului (Hungarian: Hadadnádasd), part of Hodod commune in the southeastern corner of Satu Mare County. Hodod commune lies in the hills of Codru, approximately 10 km west of Cehu Silvaniei.
Begin with the source’s own compact description: “Coșei” is river in Romania. The dossier treats that line as a proposition to test through Coșei, river and Romania, not as a finished interpretation.
Why this record matters
The phrase “river in Romania” 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.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q7264561.
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.
