From Prague to Ulan Bator, the decade since 1989 has witnessed a revolution both deep and broad. It was simultaneously a national revolution that created new nation-states, a political revolution that sundered the most fully institutionalized authoritarian regimes of the twentieth century, and an economic revolution that replaced administered systems of production and distribution with markets. Separate national, democratic, and capitalist revolutions that had rocked western European countries in the eighteenth, nineteenth, and early twentieth centuries swept almost in an instant across nine countries that quickly became twenty-eight.
