This agreement ushered in a period of 40 years of peaceful relations between the two powers. During the first years of his reign, Peter I faced revolts by two of his three brothers, John in 928 and Michael in 930, but both were quelled. During most of his subsequent rule until 965, Peter I presided over a Golden Age of the Bulgarian state in a period of political consolidation, economic expansion and cultural activity.
