Source-derived summary

Year 1245 (MCCXLV) was a common year starting on Sunday of the Julian calendar.

Events

By place

Europe

Winter – Siege of Jaén: Castilian forces under King Ferdinand III ("the Saint") besiege the Moorish-held city of Jaén. During the siege Moorish knights sally out and manage to capture a Castilian supply caravan. Meanwhile, Ferdinand tries to launch attacks on the various city gates, but all are ineffective.

In witness of the toll taken by war and fiscal pressure in the Kingdom of Castile, the region of Segovia is described this year as depopulated and sterile.

England

King Henry III starts the work of rebuilding Westminster Abbey, as a tribute to Edward the Confessor.

Levant

April – Egyptian forces under As-Salih Ayyub besiege the city of Damascus. After six months, As-Salih Ismail, ruler of Damascus, surrenders to Ayyub in return for a vassal-principality, consisting of Baalbek and the Hauran. Ayyub is awarded the title of sultan by Caliph Al-Musta'sim in Baghdad.

By topic

Religion

February 21 – Thomas, bishop of Turku (modern Finland), is granted resignation by Pope Innocent IV. He admits to committing several felonies, such as torturing and forging a papal letter.

Editorial summary

Begin with the source’s own compact description: “1245” is year. The dossier treats that line as a proposition to test through year, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1245—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, year is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “year” 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

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 24, 2026. The linked authority identifier is Q5440. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1245.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
