Book excerpt: Rising from nomadic origins as Turkish tribesmen, the powerful and culturally prolific Seljuqs and their successor states dominated vast lands extending from Central Asia to the eastern Mediterranean from the eleventh to the fourteenth century. Supported by colour images, charts, and maps, this volume examines how under Seljuq rule, migrations of people and the exchange and synthesis of diverse traditions-including Turkmen, Perso-Arabo-Islamic, Byzantine, Armenian, Crusader and other Christian cultures-accompanied architectural patronage, advances in science and technology and a great flowering of culture within the realm. It also explores how shifting religious beliefs, ideologies of authority, and lifestyle in Seljuq times influenced cultural and artistic production, urban and rural architecture, monumental inscriptions and royal titulature, and practices of religion and magic. It also presents today's challenges and new approaches to preserving the material heritage of this vastly accomplished and influential civilization.
