Diamond begins by assessing the "third wave" of global democratization that began in 1974. With a wealth of quantitative data and case illustrations, he shows that the third wave has come to an end, leaving a growing gap between the electoral form and the liberal substance of democracy. This underscores the hollow, fragile state of many democracies and the imperative of concolidation. He then defines the concept of democratic consolidation and identifies the conditions that foster it. These include strong political institutions, appropriate institutional designs, decentralization of power, a vibrant civil society, and improved economic and political performance.

If new and troubled democracies are to be consolidated, Diamond argues, they must become more deeply democratic -- more liberal, accountable, and responsive to their citizens. Drawing on extensive public opinion research in developing and postcommunist states, he demonstrates the importance of freedom, transparency, and the rule of law for generating the broad legitimacy that is the essence of democratic consolidation. The book concludes with a hopeful view of the prospects for a fourth wave ofglobal democratization.
