In May 1625 a French-Savoian army briefly laid siege to Genoa. Though it was eventually lifted with the aid of the Spanish, the French would later bombard the city in May 1684 for its support of Spain during the War of the Reunions. In-between, a plague killed as many as half of the inhabitants of Genoa in 1656–57. Genoa continued its slow decline well into the 18th century, losing its last Mediterranean colony, the island fortress of Tabarka, to the Bey of Tunis in 1742.
