Contemporary public administration systems in Europe, including those in countries with a unitary form of government, have undergone significant changes over the past forty years. The general trend towards decentralization affects all spheres of society, from the environment and the quality of governance to economic growth and the well-being of citizens. In the countries of the European Union, decentralization takes various forms, in some cases contributing to the efficiency of the public sector, democratization and political stability, but at the same time creating serious problems in the way of reform and ensuring equal access of citizens to social benefits.
Political decentralization in unitary states is the result of complex political processes within these countries. Unitary states today are placed in such conditions when the central authorities are forced to conduct a political dialogue with regional authorities and make all sorts of compromises in order not only to prevent conflicts, but also to avoid the possible collapse of the country. The result of this dialogue is the partial transfer of some powers to the regions, which can transfer the process of decentralization of unitary states into the category of federalization and lead to a change in the form of statehood and the general political landscape when it comes to Europe as a whole.
