How has Saudi Arabia managed to maintain its Arab and Islamic values while at the same time adopting Western technology and a market economy? How have its hereditary leaders, who govern with a mixture of political pragmatism and religious zeal, managed to maintain their power? This comprehensive history of Saudi Arabia from 1745 to the present provides insight into its culture and politics, its powerful oil industry, its relations with its neighbours, and the ongoing influence of the Wahhabi movement. Based on a wealth of Arab, American, British, Western and Eastern European sources, this book will stand as the definitive account of the largest state on the Arabian peninsula.
