Overview
Irene of Hungary (Greek: Είρήνη, born Piroska; died 13 August 1134) was a Byzantine empress by marriage to John II Komnenos. She is venerated as a saint.
Life
The name Piroska was a Hungarian derivation of the Latin name Prisca, literally meaning 'ancient', but implying 'serious' or 'grave' behaviour. 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.
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.
