 A series of three small civil wars known as the Huguenot rebellions broke out, mainly in southwestern France, between 1621 and 1629 in which the Reformed areas revolted against royal authority.The uprising occurred a decade following the death of Henry IV, a Huguenot before converting to Roman Catholicism, who had protected Protestants through the Edict of Nantes.His successor Louis XIII, under the regency of his Italian Catholic mother Marie de' Medici, was more intolerant of Protestantism.
