At that time, Truth began attending Millerite Adventist camp meetings. Millerites followed the teachings of William Miller of New York, who preached that Jesus would appear in 1843-1844, bringing about the end of the world. Many in the Millerite community greatly appreciated Truth's preaching and singing, and she drew large crowds when she spoke.
The year 1843 was a turning point for Baumfree. She became a Methodist, and on June 1, Pentecost Sunday, she changed her name to Sojourner Truth. She chose the name because she heard the Spirit of God calling on her to preach the truth. She told her friends: "The Spirit calls me, and I must go," and left to make her way traveling and preaching about the abolition of slavery.
In 1843, Douglass joined other speakers in the American Anti-Slavery Society's "Hundred Conventions" project, a six-month tour at meeting halls throughout the Eastern and Midwestern United States. During this tour, slavery supporters frequently accosted Douglass. At a lecture in Pendleton, Indiana, an angry mob chased and beat Douglass before a local Quaker family, the Hardys, rescued him. His hand was broken in the attack; it healed improperly and bothered him for the rest of his life.
After 1843, fast on the heels of the Syrian debacle, and the treaty of Balta Liman, which forced the Egyptian government to tear down its import barriers, and to give up its monopolies, Muhammad Ali's mind became increasingly clouded and tended towards paranoia. Whether it was genuine senility or the effects of the silver nitrate he had been given years before to treat an attack of dysentery remains a subject of debate.
