Source-derived summary

The 6000-mark war was a war between Denmark and Sweden which took place from 1276 to 1278. It started because of a disagreement over an agreed sum of 6,000 silver marks for Danish assistance to Magnus Birgersson in the battle against Valdemar Birgersson in 1275.

Editorial summary

Begin with the source’s own compact description: “6000-mark war” is war between Sweden and Denmark (1276–78). The dossier treats that line as a proposition to test through 6000-mark, between and Sweden, not as a finished interpretation.

Editorial reviewA strong contextual entry point for chronology, institutions and public events when official records are distinguished from later interpretation. The current lead gives the account dated anchors—1276, 1278, 1275—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, 6000-mark, between and Sweden is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “war between Sweden and Denmark (1276–78)” 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.

Evidence profile

Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Aug 21, 2026. The first chronological checks are 1276, 1278 and 1275.

Critical limits

Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. 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.

How to read it

Compare institutional narratives with records created by participants and affected communities. Dates and formal titles are useful anchors, but not substitutes for context.
