The Muslim Brotherhood is the oldest and most important international Islamist group. Aside from strong organizations in Egypt, Jordan, Syria - where it provides the main opposition - and its Palestinian offshoot Hamas which rules the Gaza Strip, the Brotherhood has become active in Europe and North America. Its flexible tactics which range from terrorism through electoral participation to social welfare activities have made it a particularly effective group. This book is the first comprehensive analysis of the Brotherhood's organizations, doctrine, and leaders in all the main countries where it operates.
