This part introduction presents an overview of the key concepts discussed in the subsequent chapters. The part explores head-on one of the most profound divides that continues to articulate global politics and that is key to understanding the differential experiences of people across the planet and the governance systems that they encounter. It explores how social hierarchies are continually reconstituted in systems of governance at all levels and the silences and violences embedded in their underlying processes. The part describes the use of discourses of Otherness and inclusion in the United States and elsewhere, which has implications for global governance more generally; and she shows how at the same time that diversities of gender, race, nationality, sexuality, religion, class, and dis/ability have become essential components in determining who governs, how governance works, and what constitutes the very subject of governance itself, it has also been an era of growing violence toward them.
