Peter I was Simeon’s son and successor. His period includes literary centres and Christian communities. Saints’ Lives, texts about a holy person, connect him with Ivan of Rila. Their miraculous episodes should be read as religious narratives, rather than a record made at a meeting. Succeeded Simeon in 927. Ruled during part of Preslav’s cultural flourishing. Appears in the Lives of Ivan of Rila. Books and saints’ Lives help distinguish his reign from later memories of it.
