Francesco Podesti, 1844. It depicts the Siege of Ancona of 1174 , Stamira After 1000, Ancona became increasingly independent, eventually turning into an important
maritime republic, often clashing against the nearby power of the
Republic of Venice. Ancona had to guard against the designs of both the
Holy Roman Empire and the
papacy. It did not as a rule engage in offensive warfare against rival republics, but was frequently forced to defend itself. Venice never succeeded in subduing Ancona, despite a series of military expeditions,
trade wars, and
naval blockades Ancona was strong enough to resist attack by the Holy Roman Empire on three occasions, as the Empire sought to reassert its authority over Ancona and all Italian communes. In 1137 Ancona was besieged by
Emperor Lothair II, in 1167 by
Emperor Frederick Barbarossa, and once more in 1174. In that year,
Christian I, archbishop of Mainz and the emperor's
archchancellor, joined with
Venice to besiege Ancona but were forced to retreat. almost simultaneously
Ragusa was officially called "republic", confirming the fraternal bond that united the two Adriatic ports. Unlike other cities of
central and
northern Italy, Ancona never became a
seignory. The
Malatesta took the city in 1348 taking advantage of the
black death and of a fire that had destroyed many of its important buildings. The Malatesta were ousted in 1383.
Pope Clement VII, under the false pretext of an imminent attack on the city by the
Ottoman Turks, offered to add new fortifications to the Citadel on Colle Astagno at the papacy's expense, and sent the architect
Antonio da Sangallo the Younger. This was in fact a pretext for papal troops to occupy Ancona, as Clement was anxious to replenish the empty coffers of the papacy after the
Sack of Rome in 1527. On 19 September 1532, Ancona was occupied and, as papal troops in the Citadel aimed their cannons at the city and its main access roads, was forced to unconditionally surrender its independence; with an
ante litteram coup d'état, Pope Clement VII put an end to
de facto freedom, thus placing the city under the direct dominion of the
Papal States. == Communities in the Republic ==
