pretender to the throne of Lombardy who was pursued by Otto I, hid at Saint-Tropez. In 972, the Muslims of Saint-Tropez held Maïeul, the abbot of Cluny, for ransom. In 976, William I, Count of Provence, Lord of Grimaud, began attacking the Muslims, and in 980 he built a tower where the Suffren tower now stands. In 1079 and 1218, Papal bulls mentioned the existence of a manor at Saint-Tropez. From 1436, Count René I (the "good King René") tried to repopulate Provence. He created the Barony of Grimaud and appealed to the Genoan Raphael de Garezzio, a wealthy gentleman who had sent a fleet of caravels carrying 60 Genoese families to the area. In return, Count René promised to exempt the citizens from taxation. On 14 February 1470, Jean de Cossa, Baron of Grimaud and Grand Seneschal of Provence, agreed that the Genoan could build city walls and two large towers, which still stand: one tower is at the end of the Grand Môle and the other is at the entrance to the Ponche. The city became a small republic with its own fleet and army and was administered by two consuls and 12 elected councillors. In 1558, the city's captain Honorat Coste was empowered to protect the city. The captain led a militia and mercenaries who successfully resisted attacks by the Turks and Spanish, succored Fréjus and Antibes and helped the Archbishop of Bordeaux regain control of the Lérins Islands. In 1577, the daughter of the Marquis Lord of Castellane, Genevieve de Castilla, married Jean-Baptiste de Suffren, Marquis de Saint-Cannet, Baron de La Môle, and advisor to the parliament of Provence. The lordship of Saint-Tropez became the prerogative of the De Suffren family. One of the most notable members of this family was the later vice-admiral Pierre André de Suffren de Saint-Tropez (1729–1788), veteran of the War of the Austrian Succession, the Seven Years' War and the American Revolutionary War. In September 1615, Saint-Tropez was visited by a delegation led by the Japanese samurai Hasekura Tsunenaga that was on its way to Rome but was forced by weather to stop in the town. This may have been the first contact between the French and the Japanese. The local noblemen were responsible for raising an army that repulsed a fleet of Spanish galleons on 15 June 1637; Les Bravades des Espagnols, a local religious and military celebration, commemorates this
