Battle of Giglio

After Frederick's victory at the Battle of Cortenuova in 1237 a conflict erupted in the spring of 1239 between the Pope and the Emperor concerning the question of the Imperial claim to rule over the cities of the Lombard League, an open conflict that culminated in the second excommunication of the Emperor on March 20, 1239. From then on both sides not prepared to compromise carried the military conflict against each other, where the Emperor achieved a victory in the Papal States at the Siege of Faenza, which increasingly threatened the position of the Pope. In the fall of 1240 the Pope issued to the Church dignitaries of Italy, Sicily, Germany, France, Spain and Hungary, the invitation to a council which should be addressed at Easter 1241 in Rome consulting the next steps of the church against the Emperor. In his capacity as King of Sicily Frederick II could easily suppress participation of the Sicilian prelates, but the clergy of the other countries gathered in the following months in order to travel on to Rome. ==Battle==

of Matthew Paris (1259) The Emperor controlled the land route through central Italy and thus Rome was cut off by land from northern Italy. where they were anchored there for one or two days. When the crews learned of an attack by Oberto Pallavicino on the town of Zolasco, they intended to come to the rescue, but the two legates prevented it by successfully pushing for a quick drive to Rome. In another stopover in Porto Venere A most bloody fight then ensued at sea between the Pisans ... and the Genoese in which the Genoese were defeated, and the prelates and legates were made prisoners, with the exception of some who were slain or drowned – Matthew Paris, Chr. Maj. IV. 125. In the following engagement the Imperial fleet proved superior over that of the Genoese, especially since the numerous passengers and their luggage disabled the Genoese in the adequate defense of their ships, which could therefore provide only weak resistance to escape the threat of sinking. and capturing the notable prelates as well as the treasuries and correspondence. ==Aftermath==

The hijacking of the Genoese fleet was a great success for the Emperor Frederick II. Almost all the high dignitaries of the council got into his captivity. These included the three Papal legates; the archbishops of Rouen, Bordeaux and Auch; the bishops of Carcassonne, Agde, Nîmes, Tortona, Asti and Pavia; the abbots of Cîteaux, Clairvaux, Cluny, Fécamp, and . Only with the surprisingly fast death of Pope Gregory IX in August 1241 did the situation seemed to relax at first. As a sign of good will Frederick II had the legates released in order to make way for the election of a new Pope. The newly elected Pope Innocent IV, however, should prove to be an equally intransigent opponent as his predecessor. In 1244 he took his exile seat in safe Lyon, where this time the convocation of the First Council of Lyons was achieved, which formally deposed the Emperor. Ansaldo da Mare took advantage of the fortune resulting from this victory to acquire the lordship north of the Corsican cape. == See also ==
