The uprising occurred a decade after the death of Henry IV who, himself originally a Huguenot before converting to Catholicism, had protected Protestants through the Edict of Nantes.
Toiras reinforced the fortification of Fort Louis, instead of dismantling it, right under the walls of the Huguenot stronghold of La Rochelle, and as a strong fleet was being prepared in Blavet for the eventuality of a siege of the city.
[5] In February 1625, Soubise led a second Huguenot revolt against Louis XIII,[6] and, after publishing a manifesto, invaded and occupied the island of Ré, near La Rochelle.
Soubise then returned to Ré with 15 ships and soon occupied the Ile d'Oléron as well, thus giving him command of the Atlantic coast from Nantes to Bordeaux.
The rebels had received the backing of the English king Charles I, who sent his favourite George Villiers, 1st Duke of Buckingham with a fleet of 80 ships.
In June 1627 Buckingham organised a landing on the nearby island of Île de Ré with 6,000 men in order to help the Huguenots, thus starting an Anglo-French War (1627–1629), with the objective of controlling the approaches to La Rochelle, and of encouraging the rebellion in the city.
[3] Residents of La Rochelle resisted for 14 months, under the leadership of the mayor Jean Guiton and with gradually diminishing help from England.
By the terms of the Peace of Alais, the Huguenots lost their territorial, political, and military rights, but retained the religious freedom granted by the Edict of Nantes.
However, they were left at the mercy of the monarchy, unable to resist when the next king, Louis XIV, embarked on active persecution in the 1670s, and revoked the Edict of Nantes in 1685.
As a consequence, the Huguenots lost their political power, helping to strengthen the central government, which continued on a path toward absolutism.
