In this comprehensive and up to date history, from prehistoric proto-Indo-Iranian times to the post-Soviet period, Richard Foltz traces the complex linguistic, cultural and political history of the Tajiks, a Persian-speaking Iranian ethnic group from the modern-day Central Asian states of Tajikistan, Afghanistan, and Uzbekistan. In eight chapters, the author explores the revitalisation of Persian culture under the Samanid Empire in the Tajik heartlands of historical Khorasan and Transoxiana, analyses the evolution of the politics of Tajik identity, and traces the history of the ethnic Tajik diaspora today.
