Following the expulsion of John Calvin and William Farel from Geneva in 1538, Marguerite de Navarre wrote to Marie Dentière, a notable French Protestant reformer in Geneva. The two women appear to have personal history outside of their written correspondence: Marguerite was godmother to the daughter of Marie Dentière and Dentière's daughter composed a French guide to the Hebrew language to send to Marguerite's daughter. In her letter, Marguerite inquired what was the cause for Calvin and Farel's expulsion. Dentière responded in 1539 with the "Epistre tres utile", commonly known today as the "Epistle to Marguerite de Navarre". This epistle criticized the Protestant clergy who had expelled Calvin and Farel, asked for Marguerite's support and aid in increasing scriptural literacy and access among women, and advised her to act in expelling Catholic clergy from France.
