Autobiographical works are by nature subjective. The inability—or unwillingness—of the author to accurately recall memories has in certain cases resulted in misleading or incorrect information. Some sociologists and psychologists have noted that autobiography offers the author the ability to recreate history.
Spiritual autobiography is an account of an author's struggle or journey towards God, followed by conversion a religious conversion, often interrupted by moments of regression. The author re-frames his or her life as a demonstration of divine intention through encounters with the Divine. The earliest example of a spiritual autobiography is Augustine's Confessions though the tradition has expanded to include other religious traditions in works such as
Zahid Rohari's An Autobiography and Black Elk Speaks. The spiritual autobiography works as an endorsement of his or her religion.
A memoir is slightly different in character from an autobiography. While an autobiography typically focuses on the "life and times" of the writer, a memoir has a narrower, more intimate focus on his or her own memories, feelings and emotions. Memoirs have often been written by politicians or military leaders as a way to record and publish an account of their public exploits. One early example is that of Julius Caesar's , also known as Commentaries on the Gallic Wars. In the work, Caesar describes the battles that took place during the nine years that he spent fighting local armies in the Gallic Wars. His second memoir, (or Commentary on the Civil War) is an account of the events that took place between 49 and 48 BC in the civil war against Gnaeus Pompeius and the Senate.
Leonor López de Córdoba (1362–1420) wrote what is supposed to be the first autobiography in Spanish. The English Civil War (1642–1651) provoked a number of examples of this genre, including works by Sir Edmund Ludlow and Sir John Reresby. French examples from the same period include the memoirs of Cardinal de Retz (1614–1679) and the Duc de Saint-Simon.
The term "fictional autobiography" signifies novels about a fictional character written as though the character were writing their own autobiography, meaning that the character is the first-person narrator and that the novel addresses both internal and external experiences of the character. Daniel Defoe's Moll Flanders is an early example. Charles Dickens' David Copperfield is another such classic, and J.D. Salinger's The Catcher in the Rye is a well-known modern example of fictional autobiography. Charlotte Brontë's Jane Eyre is yet another example of fictional autobiography, as noted on the front page of the original version. The term may also apply to works of fiction purporting to be autobiographies of real characters, e.g., Robert Nye's Memoirs of Lord Byron.
