Independent female evangelism thrived during the 1860s, a period of sustained evangelical activity promoting religious revival. This chapter traces the transatlantic roots of revivalism, the prominence of women within it, and the emergence of a group of female evangelists who developed professional careers outside the formal ministry. In particular, it describes the careers of the small number who achieved national prominence. Most were not Methodists but often spoke in Methodist chapels, and three of them—Catherine Booth, Isabella Armstrong, and Geraldine Hooper—published justifications for female preaching. While independent female evangelism waned by the end of the decade, the Salvation Army, co-founded by Catherine Booth, provided unprecedented opportunities for female religious leadership.
