In the diploma thesis entitled "Process of national construction of the contemporary Croatian state" the main guidance is the process of building the modern Croatian state through the idea of a nation, as a project that throughout its course had clear guidelines and followed a specific idea. The processes that marked the Croatian national identity have been happening for centuries, and in this paper, partly chronologically, a picture of the emergence of the Croatian national identity will be created, with special attention to the identity of the modern Croatian state. All these processes are connected by the same or similar idea about the Croatian name and the national solution to the Croatian question, which led to the modern Croatian state. The continuation of the same process is the role of Croatia in Euro integration and the general status of Croatia in the globalized world. All elements of Croatian statehood, historical events and current engagement are one continuous process of building the Croatian state from the Middle Ages to modern times. With the conclusion that all these elements, which are connected and explained through almost all social sciences, were necessary for what the Croatian people achieved through that process.
