Human rights refer to the philosophical, legal and political idea by which a human being by birth, regardless of gender, citizenship or origin, acquires inalienable human rights. The process of protecting human rights is very complex. In the 20th century, within the United Nations, inalienable and fundamental rights are established and established that apply equally to every human being. The protection of human rights presupposes a change in approach to society, the individual, the authorities and the state through the Constitution and laws, international documents, procedures and institutions, which strengthen protection against discrimination, corruption, arbitrariness, intolerance, inefficiencies of that inequality. The greatest protection of human rights at the national level is certainly provided by the Constitutional Court of the Republic of Croatia, which ensures the rule of law, respect for and application of the Constitution and the protection of human rights and fundamental freedoms through a constitutional complaint are guaranteed. On a supranational basis, there is a European Court of Human Rights dealing with lawsuits related to violations of rights guaranteed by the European Convention for the Protection of Human Rights and Fundamental Freedoms. The purpose of this paper is to clarify the types and characteristics of human rights, to describe their history, and to clarify human rights in administrative proceedings. In addition, one of the goals of the paper is to explain the protection of human rights in the Republic of Croatia, to touch on the Constitution and the Constitutional Court of the Republic of Croatia and the Ombudsman, but also highlight the protection of human rights in the European Union and explain the proceedings before the European Court of Human Rights.
