In 1571 the city of La Rochelle suffered a naval blockade by the French Navy under the command of Filippo di Piero Strozzi and Antoine Escalin des Aimars, a former protagonist of the Franco-Ottoman alliance. The city was finally besieged during the Siege of La Rochelle (1572-1573) during the French Wars of Religion, following the St. Bartholomew's Day massacre in August 1572, and occurred at the same time as other sieges of Protestant cities such as the Siege of Sancerre. The conflict ended with the 1573 Peace of La Rochelle, which restricted the Protestant worship to the three cities of Montauban, Nîmes and La Rochelle. Pierre Richier died in La Rochelle in 1580.
