This development grew out of the exigencies of the First World War, where faster and better co-ordinated decisions across Government were seen as a crucial part of the war effort. Decisions on mass conscription, co-ordination worldwide with other governments across international theatres, and armament production tied into a general war strategy that could be developed and overseen from an inner "War Cabinet". The country went through successive crises after the war: the 1926 United Kingdom general strike; the Great Depression of 1929–32; the rise of Bolshevism after 1917 and Fascism after 1922; the Spanish Civil War 1936 onwards; the invasion of Abyssinia 1936; the League of Nations Crisis which followed; and the re-armament and resurgence of Germany from 1933, leading into another World War. All these demanded a highly organised and centralised Government centred on the Cabinet.
