Biography

A biography, or simply bio, is a detailed description or account of a person's life. It involves more than just basic facts like education, work, relationships, and death. It portrays a person's experience of these life events. Unlike a profile or curriculum vitae (résumé), a biography presents a subject's life story, highlighting various aspects of their life, including intimate details of experience, and may include an analysis of the subject's personality.
Biographical works are usually non-fiction, but fiction can also be used to portray a person's life. One in-depth form of biographical coverage is called legacy writing. Works in diverse media, from literature to film, form the genre known as biography.
An authorized biography is written with the permission, cooperation, and at times, participation of a subject or a subject's heirs. An unauthorized biography is one written without such permission or participation. An autobiography is written by its subject, sometimes with the assistance of a collaborator or ghostwriter.
History
At first, biographical writings were regarded merely as a subsection of history with a focus on a particular individual of historical importance. The independent genre of biography as distinct from general history writing, began to emerge in the 18th century and reached its contemporary form at the turn of the 20th century.[1]
Historical biography

Biography is the earliest literary genre in history. According to Egyptologist Miriam Lichtheim, writing took its first steps toward literature in the context of the private tomb funerary inscriptions. These were commemorative biographical texts recounting the careers of deceased high royal officials.[2] The earliest biographical texts are from the 26th century BC.
In the 21st century BC, another famous biography was composed in Mesopotamia about Gilgamesh. One of the five versions might be historical.
From the same region a couple of centuries later, according to another famous biography, departed Abraham.
