Book excerpt: In this book, Ali Gheissari and Vali Nasr look at the political history of Iran in the modern era, and offer an in-depth analysis of the prospects for democracy to flourish there. After having produced the only successful Islamist challenge to the state, a revolution, and an Islamic Republic, Iran is now poised to produce a genuine and indigenous democratic movement in the Muslim world. Democracy in Iran is neither a sudden development nor a western import, and Gheissari and Nasr seek to understand why democracy failed to grow roots and lost ground to an autocratic Iranian state.
