Book excerpt: The book Security, Identity and Global Hegemony examines the themes contained in the volume and is a study tool through valuable research for experts, teachers, as well as students, but most importantly these ideas reach the individuals that governments govern. Security, Identity and Global Hegemony presents an overview of the institutional security architecture, exploring some of the key contemporary challenges to global security, but also specific issues generating insecurity in different geopolitical areas. In geopolitical literature, the hegemony refers to domination or leadership, particularly in relations between states, but after Antonio Gramsci's theory, the term refers to features of class relations to specifying a particular relationship between domination and leadership. The effects influence not only the individual, but also the ethnic or national security and identity. The 20 authors, researchers and professors in various academic centers include theoretical approaches from both traditional and critical standpoints and explain fundamental concepts underpinning contemporary focal topics.
