Events
By place
Byzantine Empire
Spring – Emperor John II Komnenos and his sons lead a Byzantine expeditionary force across Anatolia to Antalya. He drives back the Seljuks and Turcomans – who again are trying to invade Phrygia. John strengthens the frontier defences in northern Syria and sends an embassy to Germany – to seek an alliance against King Roger II of Sicily. To seal the alliance, the emissaries request that King Conrad III send a princess of his family to be married to the emperor's son, Manuel. Instead, Conrad selects his sister-in-law, Bertha of Sulzbach, and sends her to the Byzantine Empire escorted by Emicho, bishop of Würzburg.
Late Summer – John II establishes a supply base for his further campaigns at Antalya. While waiting for reinforcements, his eldest son Alexios and appointed heir, falls ill and dies. His other two sons, Andronikos and Isaac are tasked to escort the body, but during the voyage Andronikos also dies. John continues his campaign against the Armenian kingdom of Cilicia – to re-conquer the fortresses that the Danishmends have taken.
Begin with the source’s own compact description: “1142” is year. The dossier treats that line as a proposition to test through year, not as a finished interpretation.
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.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 2, 2026. The linked authority identifier is Q19614. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1142.
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.
