This is due to the different historical ways of forming state institutions in these countries, as well as the significance and functions of the sovereign at the present stage. The British monarchy is one of the richest in Europe. The Royal family has both public funds allocated annually and private property and assets. The main source of subsidies from the budget is the Crown Estate, which was actually transferred by the monarch to the executive authorities more than two hundred years ago. At the same time, funds allocated to the Royal family in the Netherlands are strictly regulated. They are distributed among three groups of expenditures, the amount of funding for each of which is strictly limited. Public funds are also allocated to provide for only four members of the Royal family, whose right to public funding is enshrined in the country's Constitution. The Principality of Liechtenstein is a unique case, since the ruling family does not receive any funds for its existence from the country's budget. The princely house is completely self-sufficient due to large assets, income from land ownership and its own banking business. The author analyzes and reveals the relationship between the financial situation of the monarchs of the countries under consideration, their level of dependence on state allocations and the political power they exercise.
