During the interwar period in Europe, internal disturbances were not an uncommon form of domestic tension and conflict. This paper looks into the concept and characteristics of domestic disturbances in Lithuania in the period 1918 to 1940. The aim is to show the opportunities for organising such disturbances and the legal regulation of their control, including the use of the army to quell them. The legal regulation of the possibilities to use the army during the disturbances, and the situational circumstances of using troops in such cases in Lithuania, are compared with similar cases in other East-Central European countries, such as Estonia, Latvia and Poland.
