Source-derived summary

The Battle of Monte Porzio was fought on 29 May 1167 between the Holy Roman Empire and the Commune of Rome. The communal Roman army, which one historian has called the "greatest army which Rome had sent into the field in centuries", was defeated by the forces of the Emperor Frederick Barbarossa and his local allies, the Counts of Tusculum and the ruler of Albano. Comparing its effect on the city of Rome, one historian has called Monte Porzio the "Cannae of the Middle Ages".

Editorial analysis

Why this record matters

The subject matters to the history & society register because the source frames it as 1167 battle between the Holy Roman Empire and the Commune of Rome. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 21, 2026. The first chronological checks are 1167.

Critical limits

Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. 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.

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.
