Treaty of Neuilly-sur-Seine
The Treaty of Neuilly-sur-Seine proved to be a severe blow to Bulgaria's military. According to the treaty, the country had no right to organize a conscription-based military. The professional army was to be no more than 20,000 men, including internal forces and border guards. Equipping the army with tanks, submarines, bombers and heavy artillery was strictly prohibited, although Bulgaria managed to get around some of these prohibitions. Nevertheless, on the eve of World War II the Bulgarian army was still well-trained and well-equipped.
