The aim of the article is to study the dependencies in the development of economic potential of states and increase their military power, on the example of the historical development of Germany and Japan in the second half of the 19th century and early 20th century. The article examines and identifies trends in socio-economic and political development of the two countries, as well as their impact on the formation of military power of states. The analysis of the sources shows that the issue of developing the military and economic power of the states is given a lot of attention, especially the interest in this issue began to grow with the beginning of the war in Syria and Ukraine. The vast majority of countries in the world are gradually increasing their defense budgets, thus increasing global military power and tension. The issue of military power is increasingly receiving the attention of the top political leadership of the advanced states of the world, which cannot but arouse the interest of scientists. Research on historical analogies, identical to past events, can help identify patterns and predict scenarios for future events, which will help states better prepare for the future
