The 17th century of the Dubrovnik Republic can be remembered as an extremly dramatic and dynamic period, thanks to the natural disaster as such as the big earthquake in 1667. and diplomatic battle after the earthquake. The survival and reconstruction of the city after 1667. was led by exceptional diplomats that were in great political relations and connections with other countries, such as Turkey, Spain, Austria and the Vatican, protected the national, commercial, and political interests of Dubrovnik. The foundation of Dubrovnik’s diplomacy is founded by maintaining neutrality, compromise, and agreement with everyone. Thanks to this type of politics, little Dubrovnik was the key factor of stability and peaceful cooperation on the whole southeastern European area, much sooner than these facts took place in the politic theories and practice in other countries. Diplomats Nikolica Bunić, Marojica Kaboga, and Stjepan Gradić contributed to the survival of the Republic after the earthquake, because they had the political wisdom, bravery and discretion for the moves that saved Dubrovnik. Every diplomatic action was proven successful, i.e. consultations with the pope and the cardinal Barberini, diplomatic offensive with the Venetians, and the treaty with Kara Mustafa, all these contributed to the survival and reconstruction of the city from then until today.
