The subject of the research is the foreign policy of Great Britain in the late 19th – early 20th centuries and the continuity of the foreign policy course of liberal political figures. The purpose of the analysis is the views and activities of significant British liberal politicians on foreign policy issues against the background of the transformation of the philosophy of liberalism and unprecedented
 competition in colonial expansion among major European powers. A number of trends in the development of the political and ideological course of the Liberal Party of Great Britain are demonstrated - a quick rejection of the policy of
 «Splendid Isolation» to the search for friendly powers on the European continent and the direct influence of liberal-imperialist circles on changing the foreign policy strategy. The study of sources confirms that as part of the evolution of the philosophy of liberalism at the end of the 19th century, the idea of the foreign
 policy of Great Britain in the circles of liberal politicians of the country also changed. The author comes to the conclusion that after W. Gladstone left power, the liberals hastened to move away from the policy of «Splendid Isolation». A. Rosebery tried to maintain a balance of power, but, as an adherent of liberal
 imperialism, he actively used military force, not striving to be the first to establish friendship with anyone in Europe. During the period of opposition 1896-1905 not only liberal-imperialists such as E. Grey, H. Asquith, R. Haldane, but also pacifists such as H. Campbell-Bannerman came to the conclusion that a world conflict was inevitable against the backdrop of growing disagreements with Germany and the need to choose an ally in Europe.
