Book excerpt: This book examines the changing nature of global inequalities and efforts that are being made to move toward a more egalitarian world society. The contributors are world historical sociologists and geographers who place the contemporary issues of unequal power, wealth and income in a global historical perspective. The geographers examine the roles of geopolitics and patterns of warfare in the historical development of the modern world-system, and the sociologists examine endeavours to improve the situations of poor peoples and nations and to engage the challenges of sustainability that are linked with global inequalities. Overcoming Global Inequalities contains cutting-edge research from engaged social scientists intended to help humanity deal with the challenges of global inequality in the 21st century.
