The article studies the main stages and features of the evolution of the public administration system in the Republic of Estonia after 1992. This paper presents brief geographical and socio-economic characteristics that largely determine the development of the country’s public administration. The evolution of the institution of the presidency, executive, and legislative powers are considered. The role of parliament and mechanisms for coordinating the interests of different groups of the population for the development of the country is especially emphasized. The authors analyze the state and administrative reforms of recent years, which were aimed at improving the quality of services provided to the population, increasing the competitiveness of different parts of Estonia, as well as optimizing public spending and management structure. The introduction of digital technologies into the sphere of public administration, healthcare, education, and the social sphere is of a notable place. Such phenomena as e-residency, e-federation, and other digital projects are considered. The development of a digital system of interstate interaction between Estonia and Finland made it possible to create the world’s first e-federation, and the digitization of all strategically important information and its transfer to cloud storage speaks of the creation of the world’s first e-residency, a special residence of data outside the country’s borders to ensure digital continuity and statehood in the event of critical malfunctions or external threats.
