Conrad III

   German king (1138-1152), first of the Hohenstaufen dynasty. His alliance in 1140 with John II Komnenos against the Normans (qq.v.) was sealed with the marriage of Conrad III's sister-in-law, Bertha of Sulzbach (q.v.) to John II's son Manuel I (q.v.) in 1146. This alliance was the cornerstone of Byzantine policy in the West, a policy that aimed at destroying Norman power in southern Italy (q.v.). After 1130, when Roger II (q.v.) united Apulia and Sicily (qq.v.) into a single realm called the Kingdom of Sicily, Norman power increased substantially. Unfortunately, this policy unraveled when Conrad III advanced on Constantinople (q.v.) in 1147 with the Second Crusade (q.v.), diverting his attention from Europe, and allowing Roger II to seize Kerkyra (q.v.) and pillage Corinth, Thebes, and Euboea (qq.v.). Conrad returned from the Second Crusade too ill to carry out a combined Byzantine and German campaign against the Normans in Italy.
