Siege of Genoa (Premysloides Dynasty)

Background
Siege of Genoa was direct consequence of fatal betrayal which occured during Siege of Venice. In middle of battle, Genoese Fleet unite with remnants of Venice to destroy Roman Empire and their allies. However, Emperor Romanos did not panicked and was able not only repel Genoese-Venetian navy counter-attack, but also decimated Genoese and Venetian fleet and achieve victory in Venice Lagoon. After that, he decided to take part of his naval forces, rest of forces remained in Siege of Venice and he with small fraction of ships went to Genoa.

Siege
To these days, Siege of Genoa is considered as shortest battle ever, and if we count it as separate conflict, also shortest war. Whole "war" happened only for 27 minutes during which imperial fleet bombarded Genoa, destroyed shipyards and ports and forced Genoese to negotiation of capitulation.

Aftermath and peace treaty
Imperial Restoration did not end only Venetian, but also Genoese rule over Mediterranean Sea. Genoese Doge Ignacio Geppola, genoese grandadmiral Calavra and genoese grand-guildmaster Jorgos negotiated on Emperor Flagship about conditions of peace.

Imperial-Genoese Peace Treaty

In accordance between Republican Rulling Triumvirate of Republic of Genoa and Emperor Romanos IV Angelos-Premysloides of Roman Empire, Republic of Genoa agree with following conditions: Signed: Romanos IV Angelos-Premysloides, Doge Ignacio Geppola, Grandadmiral and Supreme Commander of Genoese Naval Forces Julio Calavra, Grandmaster of Genoese Guilds Luigi Jorgos.

While this treaty did not led to formal annexation of Republic of Genoa by imperial rule, in fact Republic of Genoa was destroyed, especially under influence of "Imperial Province of Liguria", which had strong support from Empire and had destructive influence on remnants of Republic of Genoa. Genoa never restored and in 1287, Genoa officially accepted imperial rule and incorporated its territory to Imperial Province of Liguria.

Historical discussion
For many times, discussion among historians occured about reasons of Genoese betrayal and consequences. Martin Waldez, Dean of University of Constantinople belive that Genoa was under influence of Venetian Republic through old debts and few marriage connections between Genoese and Venetian patrician families. Princess Anna Angelos-Premysloides, 14th century historian of Constantinople Imperial Palace Library disagreed and presented her own theory. According Anna Premysloides, Genoese betrayal was rash action based on possibility of total destruction of Venice and Roman Empire. If Genoa would succeed, Genoese rule over Mediterranean Sea would be total and undisputable. For neither theory did not exist any historical evidences, as all patrician families of Genoa extincted or were not connect to this events and Republic of Genoa Archive was destroyed by imperial navy.
