In the twentieth century, there occurred two major changes of international orders which followed respectively the end of a colonialism and the beginning of a collective security system. Colonialism remained the basis of European expansion and domination for more than four centuries and a half until the middle of the twentieth century, when it was put to an end. Collective security was first institutionalized by the League of Nations and then succeeded and developed by the United Nations. Each of the two is responsible for a broad and deep change of attitude of nations concerning war and security.
