Public administration is a set of state institutions that mainly exercises the functions of the executive body (rather than legislative or judicial) in accordance with the law. Public administration includes the Cabinet of Ministers, institutions subordinate to the Cabinet of Ministers as well as other independent institutions. The aim of the research is to analyse the historical development of the Cabinet of Ministers and ministries, to emphasize the main stages of development of public administration, while highlighting the problems that existed both during the period of Latvia’s first independence as well as after the restoration of the state and seeking the best possible solutions for the further development of public administration. The study will use descriptive, dogmatic, historical, comparative and analytical research methods.
