Bela III of Hungary (Hungarian III. Béla, Slovak: Belo III), born in 1148, was King of Hungary circa 1172-1196. He was the son of King Geza II of Hungary and Euphrosyne (daughter of Grandprince Msitislav I of Kiev). He was the great-great-great grandfather of Isabella of France, and so he is an ancestor of the present-day British royal family. Bela III succeeded his brother Stephen III of Hungary and was crowned under the influence of his father-in-law, the Byzantine Emperor Manuel I Comnenus. Bela III married:

• Marguerite Capet, daughter of king Louis VII of France
• Constance, daughter Alfonso VII of Castile
• Agnes de Chatillon (1154-1184), daughter of Raynald of Chatillon and Constance of Antioch (joint princes of Antioch)
• Other marriages: a daughter of Manuel I and his niece Margaret Comnena
