Rad analizira koncept europskog državljanstva, njegove najvažnije aspekte i prava i slobode koje taj koncept podrazumijeva. Proučavaju se najvažniji pravni izvori europskog državljanstva: osnivački ugovori Europske unije, njene regulative i direktive, kao i dugogodišnja sudska praksa koja je imala ključnu ulogu u razvoju ovog koncepta u Europskoj uniji. Posebno se analiziraju prava i slobode europskog državljanjstva, poput prava na slobodu kretanja i prebivališta. Posebno mjesto u ovom radu zauzimaju i sudski precedenti i predmeti pred Europskim sudom pravde koji su oblikovali primjenu prava o europskom državljanstvu, i njihovom analizom ilustruje se povijesni razvoj i pravna transformacija ovog koncepta. U radu se prikazuje i ideološki aspekt europskog državljanstva: ideju europskog identiteta, njen odnos i utjecaj na koncept europskog državljanstva. The authors analyse the concept of European citizenship, its most important aspects and the rights and freedoms it encompasses. The most important legal sources of European citizenship are analysed: the founding treaties of the EU, the regulations and directives of the EU institutions, and the long-term judicial practice of the European Court of Justice that has played a key role in the development of this area of EU law. The paper further explores the rights and freedoms of European citizenship, such as the freedom of movement and residence, in order to better comprehend the complexity of European citizenship law. The paper also takes a deeper look into the case law of the ECJ, and the manner it has changed the interpretation of the law on European citizenship. By analysing certain landmark cases, the paper illustrates the historical development and legal transformation the concept has undergone. Finally, the paper explores the ideological aspect of European citizenship – the idea of European identity and its influence on European citizenship – to better understand the driving forces and ideals behind the concept
