Annie Besant was arguably the most famous, or rather infamous, woman of her age. For much of the 1870s and 1880s she promoted the secularist cause with remarkable vigour. She became a vice- president of the National Secular Society, the members of which thought almost as highly of her as they did of Charles Bradlaugh, the president. In 1889, however, she joined the Theosophical Society in a sensational move that shocked even her closest friends. Eventually she became president of the Theosophical Society, the members of which again revered her almost as much as they did its prophet, Madame Blavatsky. Besant moved from the materialist atheism of the secularists to the New Age thought of the theosophists. All of her previous biographers have emphasised the contrast between these two sets of beliefs. They have been unable to recover any coherence in her activities within the secularist, Fabian and theosophical movements. Indeed, they have spoken of her many lives, as though she wandered aimlessly, if enthusiastically, from cause to cause with no guiding theme whatsoever. When they do look for a pattern in her life, they typically turn not to her reasons for doing what she did, but rather to her hidden needs, such as to follow a dominant man or to exercise her powers. They turn to her emotional make-up to explain her final flight from reason, and they then explain her earlier commitments by reference to the emotions they have uncovered. In contrast, I hope to represent Besant's life as a reasoned quest for truth in the context of the Victorian crisis of faith and the social concerns it helped to raise. Besant, with her secularism, Fabianism and theosophy, was very much of her time, for whilst the early part of Queen Victoria's reign was shaped by a religious movement to make Britain a truly Christian nation and a political movement to make Britain a democratic nation, the later part of her reign took its shape from the need to find both a faith capable of surviving the rationalist onslaught and solutions to the social problems an extended franchise had failed to solve.
