Treaty of Neuilly-sur-Seine
With the entry of the Treaty of Neuilly-sur-Seine into force the Bulgarian armed forces suffered serious restrictions. Compulsory military service was abolished, the army was scaled down to only 20,000 men and the formation of units larger than a division was forbidden. In reality, the three army inspectorates continued to function unofficially under the name of "first-class garrisons". After 1928 these restrictions were gradually abolished and new mobilization plans were drawn, that envisaged the deployment initially of four field armies during war.
