"Respublica Ragusina" or the Dubrovnik Republic developed from the medieval Dubrovnik commune, which included the majority of today's Dubrovnik-Neretva Region. While, territorially much smaller than the other powerful states of its time, the Republic has succeeded in becoming an important subject in creation of foreign policy of the world’s superpowers. The basis of Dubrovnik’s economy was seafaring and trade that brought Dubrovnik to its peak in the 15th and 16th century when it was one of the leading powers of the world. Dubrovnik’s fleet sailed across the seas and oceans, and consequently developed the trade that stimulated the establishment of diplomatic relations with foreign countries. The subject of this paper is the state legislative development of the Republic of Dubrovnik from its establishment until its abolition in 1808. Primarily, it is important to elaborate the extremely rich history of Dubrovnik that dates back to ancient times. The history of Dubrovnik can be divided into three periods. Noteworthy is the organization of the state and the society in which each citizen understood its rights and obligations, and each governmental body was independent in its work. A special feature of the Dubrovnik Republic is its diplomacy, which has helped to preserve its territorial integrity throughout history. The Dubrovnik Republic, unlike its neighboring countries, promoted a pacifist policy, which proved to be a wise decision during numerous wars.
