Irene of Hungary (Greek: Είρήνη, born Piroska;[1] 1088 – 13 August 1134) was the Byzantine empress by marriage to John II Komnenos. She is venerated as an Eastern Orthodox saint.
The name Piroska was a Hungarian derivation of the Latin name Prisca, literally meaning 'ancient', but implying 'serious' or 'grave' behaviour.[2] She was a daughter of Ladislaus I of Hungary and Adelaide of Swabia. Her mother died in 1090 when Piroska was still a child. Her father died on 29 July 1095 and was succeeded by his nephew Coloman, King of Hungary.
In an effort to improve relations with Alexios I Komnenos of the Byzantine Empire, Coloman negotiated the marriage of Piroska to John II Komnenos. John II was the eldest son of Alexios I and Irene Doukaina. He was already co-ruler of his father since late 1092 and was expected to succeed him.
The negotiations were successful and Piroska married John in 1104. The marriage was recorded by Joannes Zonaras and John Kinnamos. Following her conversion to the Eastern Orthodox Church and settlement in Constantinople, Piroska was renamed Irene.[3]
Irene played little part in government, devoting herself to piety and her many children. She was, with her husband, the patron of the construction of the Monastery of Christ Pantokrator (Zeyrek Mosque) in Constantinople. This monastery contained three churches and a hospital of 5 wards, which was open to people of all social classes.[4]
Irene died on 13 August 1134 and was later venerated as Saint Irene.[5]
She and John had eight children. The primary source about their order of births is the chronicle of Niketas Choniates:
