reconquered by the Venetians.
In 1238 Pope Gregory IX formed an alliance between Genoa and Venice against the Empire, and consequently against Pisa too. As Pula had sided with the Pisans, the city was sacked by the Venetians in 1243. It was destroyed again in 1267 and again in 1397 when the Genoese defeated the Venetians in a naval battle.
Pula then slowly went into decline. This decay was accelerated by the infighting of local families: the ancient Roman Sergi family and the Ionotasi (1258�1271) and the clash between Venice and Genoa for the control of the city and its harbour (late 13th � 14th century ). In 1291 � by the Peace of Treviso � Patriarch Raimondo della Torre gained the city as part of the secular realm of the Patriarchate of Aquileia, only to lose it to Venice in 1331, which then held it until its downfall in 1797.
Pula is quoted by the Italian poet Dante Alighieri, who had visited Pula, in the Divine Comedy: "come a Pola, presso del Carnaro ch'Italia chiude e i suoi termini bagna" or "as Pula, along the Quarnero, that marks the end of Italy and bathes its boundaries".
Venetian, Napoleonic and early Habsburg rule
The Venetians took over Pula in 1331 and would rule the city until 1797. During the 14th, 15th and 16th centuries, Pula was attacked and occupied by the Genoese, the Hungarian army and the Habsburgs; several outlying medieval settlements and towns were destroyed. In addition to war, the plague, malaria and typhoid ravaged the city. By the 1750s there were only 3,000 inhabitants left in ancient city, an area now covered with weeds and ivy.
With the collapse of the Venetian Republic in 1797 following military defeat at the hands of Napoleon, the city became part of the Habsburg Monarchy. It was invaded again in 1805 after the French had defeated the Austrians. It was included in the French Empire's puppet Kingdom of Italy, then placed directly under the French Empire's Illyrian Provinces
