Global migration flows in the 20th century have seen the emergence of Muslim diaspora and minority communities in Europe, North America and other parts of the world. This book offers a set of new comparative perspectives on the experiences of Shi'a Muslim minorities outside the so-called 'Muslim heartland' (Middle East, North Africa, Central and South Asia). It looks at Shi'a minority communities in Europe, North and South America, Sub-Saharan Africa and East Asia and discusses the particular challenges these communities face as 'a minority within a minority'.
