Several women played leading roles in the early days of the Baháʼí Faith in America. Among them are: May Maxwell, Corinne True, and Martha Root. Rúhíyyih Khanum and a mix of male and female Hands of the Cause formed an interim leadership of the religion for six years prior to the formation of the Universal House of Justice. Later prominent women include Patricia Locke, Jaqueline Left Hand Bull Delahunt, Layli Miller-Muro, and Dr. Susan Maneck, who herself wrote books documenting the role of women in the Baháʼí Faith.
