Sergius II of Constantinople
Sergius II (; ? – July 1019) was the Ecumenical Patriarch of Constantinople from July 1001 to 1019. According to the history of John Skylitzes, he was a relative of the celebrated 9th-century patriarch Photius. In 1001, he was abbot of the Monastery of Manuel, which had been re-founded by Photius, when he was elected to fill the patriarchal see (June/July). According to the later legend, Sergius II was in the conflict with the Pope Sergius IV. According to Skylitzes, he died in July 1019. His successor was Eustathius. References
