This paper discusses why military intervention takes place in developing democracies by taking Pakistan as a case study with a focus on theoretical intricacies. There may be different theoretical explanations as to why the military imposes martial laws and takes the affairs of the state into their own hands. It discusses Samuel P. Huntington's Professionalism, Michael Desch's Structural Theory, based on internal and external threats and other theories of military takeover but what is found in the context of Pakistan but found Samuel Edward Finer's Disposition and Opportunity theory of military takeover more suitable. It suggests that the military in developing democracies where it has historically imposed martial laws is always ready to take over the country but wait for the right opportunity to come. And when the opportunity is presented in the shape of poor governance on the part of civilian leadership, the army makes a comeback and takes over the country.
