Edward Arthur Wilson, better known as Brother XII, (2 July 1878 - 7 November 1934?) was an English mystic who, in the late 1920s, founded a spiritual community located just south of the city of Nanaimo on Vancouver Island, off the west coast of British Columbia, Canada.
Wilson was born in Birmingham, England. He travelled the world as a mariner and studied world religions, preparing himself, by his own account, for a destiny that was revealed to him in a vision in the South of France in the autumn of 1924. He soon attracted a devoted following, including a group of wealthy and socially prominent individuals. Having taken the name Brother XII, he established the Aquarian Foundation in 1927. The group's beliefs were based largely upon the teachings of the Theosophical Society. Wilson encouraged his followers to build homes in his colony Cedar-by-the-Sea on Vancouver Island, British Columbia. With the goal of creating a self-sufficient community independent of the outside world, the Foundation acquired additional property on nearby Valdes and De Courcy Islands, largely through the donations of a wealthy socialite named Mary Connally from Asheville, North Carolina. Other followers gave donations, large and small, to support Brother XII's work as a spiritual teacher, as well as his political activity in support of a Democratic Senator from Alabama, James Thomas Heflin, who ultimately supported Herbert Hoover but was for a while a third-party candidate in the 1928 presidential election in the United States.
An insurrection developed within the ranks of the colony when Brother XII's critics charged that he had claimed to be the reincarnation of the Egyptian god Osiris, though he replied that he had been speaking figuratively, that Osiris and Isis were male and female principles in Nature. Still, Brother XII's misuse of Foundation funds and his extramarital affair with a woman who he claimed was his soul-mate led to the breakup of the colony. The Aquarian Foundation was legally dissolved in 1929, though he continued his work with the followers who had remained loyal to him during the crisis, as well as a number of new recruits. As time passed, he became increasingly dictatorial and paranoid, fortifying his island kingdom and reportedly accumulating a fortune in gold. His mistress, Mabel Skottowe, née Rowbotham (under the name "Madame Z"), worked the members without respite, the tasks given being considered tests of their fitness to advance spiritually. One man who had been imprisoned in a cellar on the northern end of Valdes Island managed to row to Nanaimo to report the circumstances to the British Columbia Provincial Police, who investigated, but took no further action. Eventually, as conditions deteriorated, Brother XII's core group of disciples revolted and filed legal actions against him to recover the monies they had contributed to his work. In a violent reaction, he destroyed the colony, smashing its buildings and farm equipment, and scuttling his flagship, the sailboat Lady Royal.
