This book has examined some of the pressing issues and challenges related to modernity, modernization, and globalization of the 21st century. The authors of this book are a distinguished group of social scientists from America's academia, many of whom are by-cultural and educationally trained both in the East and the West. The book has used historical and comparative perspectives and many extant sources of primary data. The authors have addressed many macro-issues such as modernity and church-state separation, America's historical role in spreading global modernity, the global expansion of democracy, the rise of a global middle class, the advent of global digital connectivity, and the recent rise of right-wing political parties in the global political landscape. The authors also examined many micro-issues such as modernization and women empowerment in India and Nigeria, the growth of a unique political culture of Islam and modernism in Sierra Leone, the problem of transition to emancipative values in the post-socialist countries of Central and Easter Europe, rise in religious hostilities in South Asia, need for modernization in dealing with minority females in America's criminal justice system, and modernity and the evolution of the rights of the disabled in America. The empirical and country studies largely support the theme of the book that modernity is a cultural and civilizational model. The global modernity has been progressing across world societies for more than two hundred years. It has been particularly remarkably advancing since the second half of the twentieth century. The world capitalist economy has become more global, world democracy has expanded, the global middle class has vastly grown, women's economic and political empowerments have widened, and global digital connectivity has increased. These social and economic transformations are far more fundamental for the future progress of democracy and global modernity. The further spread of global modernity is inevitable and irreversible. The present right-wing ideologies of nativism, localism, nationalism, fundamentalism, and divisiveness in the global political trajectory are transient and temporal peculiarities.
