A hagiography /ˌhæɡiˈɒɡrəfi/ is a biography of a saint or an ecclesiastical leader. The term hagiography may be used to refer to the biography of a saint or highly developed spiritual being in any of the world's spiritual traditions.
Christian hagiographies focus on the lives, and notably the miracles of men and women canonized by the Roman Catholic church, the Anglican Communion, the Eastern Orthodox Church, the Oriental Orthodox churches, and the Church of the East. Other religions such as Buddhism,Hinduism,Islam, Sikhism and Jainism also create and maintain hagiographical texts (such as the Sikh Janamsakhis) concerning saints, gurus and other individuals believed to be imbued with sacred power.
Hagiographic works, particularly those of the Middle Ages, can incorporate a record of institutional and local history, and evidence of popular cults, customs, and traditions. However, when referring to modern, non-ecclesiastical works, the term is often used as a pejorative reference to biographies and histories whose authors are perceived to be uncritical of or reverential to their subject.
