In fact, the rise of Germany in the last quarter of the 19th century can be seen in a whole set of macroeconomic data. In thirty years (1870-1900), its GNP grew at an average annual rate of 4.5%, with a peak of 5.5% between 1880 and 1890, against 1.9% for Great Britain.
The heart of the antagonism between the two countries lay in the rise of Germany's military power, and, more particularly, the implementation of the naval program that William II and von Tirpitz, his admiral-in-chief, considered the indispensable tool of “world politics” (Weltpolitik) that the Kaiser assigned to his country.
