South Yemen has come to be seen as a potential Al-Qaeda stronghold and at the heart of a separatist movement threatening to rip apart southern Arabia. How has this country of forbidding mountains and arid deserts gone from British colony to communist state and then to "terrorist base" in just half a century? In Yemen Divided, author and Middle East expert Noel Brehony tells for the first time the comprehensive history of the People"s Democratic Republic of Yemen (PDRY). He explains the power politics that came to form a communist republic a few hundred miles from the holiest site in Islam, and the process and conflicts that led to Yemeni unification in 1990. The impact of PDRY is still felt today as unrest continues to escalate across the south. Yemen Divided is an important book for anyone wanting to understand why Yemen, sensitive neighbor of Saudi Arabia and strategically vital to Middle East security, has veered towards massive instability.
