As the Ottoman state attempted to modernize its infrastructure and army in response to threats from the outside, it also opened itself up to a different kind of threat: that of creditors. Indeed, as the historian Eugene Rogan has written, "the single greatest threat to the independence of the Middle East" in the nineteenth century "was not the armies of Europe but its banks." The Ottoman state, which had begun taking on debt with the Crimean War, was forced to declare bankruptcy in 1875. By 1881, the Ottoman Empire agreed to have its debt controlled by an institution known as the Ottoman Public Debt Administration, a council of European men with presidency alternating between France and Britain. The body controlled swaths of the Ottoman economy, and used its position to insure that European capital continued to penetrate the empire, often to the detriment of local Ottoman interests.
In what year did the Ottoman Empire declare bankruptcy?

Anti-aircraft warfare or counter-air defence is defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action." They include ground-and air-based weapon systems, associated sensor systems, command and control arrangements and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries the main effort has tended to be 'homeland defence'.

Missile defence is an extension of air defence as are initiatives to adapt air defence to the task of intercepting any projectile in flight.
