Narragansetts were irreparable, and, despite Williams' efforts to maintain peace, a destructive war ensued, during which his home was burned to the ground. During the war, Williams, with a group of Providence citizens, facilitated and profited from the sale of a number of captured Narragansetts and Wamponoag. Relations with the Baptists Ezekiel Holliman baptized Williams in late 1638. A few years later, Dr. John Clarke established the First Baptist Church in Newport, Rhode Island, and both Roger Williams and John Clarke became the founders of the Baptist faith in America. Williams did not affiliate himself with any church, but he remained interested in the Baptists, agreeing with their rejection of infant baptism and most other matters. Both enemies and admirers sometimes called him a "Seeker," associating him with a heretical movement that accepted Socinianism and Universal Reconciliation, but Williams rejected both of these ideas. King Philip's War and death King Philip's War (1675–1676) pitted the colonists against indigenous peoples—including the Narragansett with which Williams had previously maintained good relations. Williams, although in his 70s, was elected captain of Providence's militia. On March 29, 1676, Narragansett warriors led by Canonchet burned Providence; among the structures destroyed were Williams' home. Burial Williams died sometime between January 16 and March 16, 1683, and was buried on his own property. Fifty years later, his house collapsed into the cellar and the location of his grave was forgotten. According to the National Park Service, in 1860, Providence residents determined to raise a monument in his honor "dug up the spot where they believed the remains to be, they found only nails, teeth, and bone fragments. They also found an apple tree root," which they thought followed the shape of a human body; the root followed the shape of a spine, split at the hips, bent at the knees, and turned up at the feet. The Rhode Island Historical Society has cared for this tree root since 1860 as representative of Rhode Island's founder. Since 2007, the root has been displayed at the John Brown House. The few remains discovered alongside the root were reinterred in Prospect Terrace Park in 1939 at the base of a large stone monument. Separation of church and state Williams was a staunch advocate of separation of church and state. He was convinced that civil government had no basis for meddling in matters of religious belief. He declared that the state
