The years 1910 to 1932 represent a key period for the study of military politics in a country which has prided itself on its armed forces for their professional, constitutional and non-interventionist tradition. Existing studies of the subject, while providing much detail on the background, development and outcome of the 1924 military intervention which is the central landmark of the period, have concentrated predominantly on army affairs and events in the capital, taking the metropolitan view. The substance and contention of this article is that the navy, and events outside the capital, exerted a significant influence on developments. The contention calls for an examination of the anatomy of the navy, the evolution of its influence, and the sources of conflict which it harboured.
