The study required by each unit will contribute to an understanding of major historical developmentsfollowing 1945. The question that unifies the studies, and towards which each must contribute, is, “Hashumanity emerged into a world whose actions are governed more by interdependence at the global level thanby dependence or independence at the national or international level?” The concept of power and the role ithas played in the social, economic, and political history of the period is foundational to studying thisquestion. Consistent attention to the varied requirements of this comprehensive and cohesive historical studywill enable students to propose reasonable answers to the question upon which Nova Scotia’s Global Studiescourses are built: “How did the world arrive at its current state at the close of the 20th century?”
