Between 1870 and 1914, armies in Europe, particularly those of Germany, France, Russia, and Austria-Hungary, significantly increased in size due to rising militarism and tensions. This military buildup was largely prompted by the need to prepare for potential conflicts, especially in response to Germany's growing power. The naval rivalry between Germany and Britain also played a crucial role during this period.
