==== Byzantine Empire ====
* Spring &ndash; Emperor [[John II Komnenos]] and his sons lead a Byzantine expeditionary force across [[Anatolia]] to [[Antalya]]. He drives back the [[Seljuk Empire|Seljuks]] and [[Turkmens|Turcomans]] – who again are trying to invade [[Phrygia]]. John strengthens the frontier defences in northern [[Bilad al-Sham|Syria]] and sends an embassy to [[Kingdom of Germany|Germany]] – to seek an alliance against King [[Roger II of Sicily]]. To seal the alliance, the emissaries request that King [[Conrad III of Germany|Conrad III]] send a princess of his family to be married to the emperor's son, [[Manuel I Komnenos|Manuel]]. Instead, Conrad selects his sister-in-law, [[Bertha of Sulzbach]], and sends her to the [[Byzantine Empire]] escorted by [[Emicho|Emicho of Leiningen]], bishop of [[Prince-Bishopric of Würzburg|Würzburg]].<ref>[[Steven Runciman]] (1952).
