His Grace the Right Reverend Bishop Peter (Ekaterinovsky) of Novoarkhangelsk became the vicar bishop of the Alaskan see as the missionary environment of the Eastern Siberia and Alaska evolved during the mid-nineteenth. Originally, arriving in Alaska in 1857 as the rector of the Novoarkhangelsk (Sitka) Seminary, Bp. Peter succeeded in 1859 to the vicariate see of Novoarkhangelsk in the Diocese of Kamchatka, the Kuriles, and the Aleutians Islands under Bp. Innocent (St. Innocent of Alaska) whose see had been moved from Alaska to Yakutsk, Russia. Following in the work of his predecessor, he added mission schools in Kodiak and Unalaska and continued missionary efforts.
