During his reign as grand sachem, Massasoit never permitted the Pokanoket to convert to Christianity, and with great diplomatic skill, managed to stay such efforts. Perhaps unsurprisingly however, the half century of peace that Massasoit so assiduously negotiated collapsed soon after his death. Breaking with his father's diplomacy, and in response to increasing depredations into Wampanoag territory by his ally, Massachusetts Bay Colony, Wamsutta began to form an alliance with Connecticut Colony. Within a year of his succession, and almost immediately after appearing in front of the court in 1662, Wamsutta died suddenly. Metacom, Massasoit's second son, became sachem of the Pokanoket, and chief sachem of the Greater Wampanoag Confederacy. Metacom, also known as Philip, certainly believed that Wamsutta had been murdered at the hands of the English. Wamsutta's death was one of the leading factors that eventually led to King Philip's War, the bloodiest war in American history — indeed, more so than the American Civil War in terms of lives lost proportional to population.
