CEVAP:

With the dawning of the 14th century, and the decline of feudalism, the period of a new economic, social and thus political transition began. The Hundred Years’ War (1337-1457) raised the need for large military forces, including the mercenary contingents. This, in turn, required the development of a centralized governmental mechanism (Gabriel and Metz, 1992: 73). In the 15th century, Europeans began to make enormous improvements in both guns and ships, starting a new phase of war (Moses, 2012: 28). By the time of the Thirty Years’ War (1618-48) all the major elements of the modern army had been set into place, which, in turn, ended with the new era of the modern inter-state system.
