Apologia (from Greek ἀπολογία, "speaking in defense") is a formal defense of a position or action. The word's currency derives from J.H. Newman's Book Apologia pro Vita Sua (Latin: A defense of one's own life), which presented a formal defense of the history of his Christian life leading to his acceptance by the Catholic Church in 1845. In modern usage, apologia describes a formal defense and should not be confused with the sense of the word 'apology' as the expression of regret.
The etymology of apologia (Greek: ἀπολογία) is derived from the root word apologos (ἀπόλογος), “a speech in defense”., and the corresponding verb apologeisthai " to speak in one's defense."  The Greek philosophers Plato, Isocrates, and Aristotle described apologia as an oratory to defend positions or actions particularly the sense of a legal defense.
The earliest English use of apologia followed from the Greek sense "providing a defense", but subsequently a parallel meaning emerged with the sense "frank expression of regret", first recorded in 1590. The parallel sense expressing regret eventually became the predominant usage until the 18th century where the older Latin meaning, first recorded in 1784, emerged, particularly since J.H. Newman's Book Apologia pro Vita Sua.

Lawrence Rosenfield’s Mass-Media Characteristics
Lawrence Rosenfield examines apologies covered by mass media. In his analysis of speeches by ex-President Harry Truman and vice presidential candidate Richard Nixon, Rosenfield described four initial characteristics of mass-mediated apologia.
1. They tend to be short and sharp clashes
2. The remarks are not solely defensive messages
3. They include an extensive amount of data in the middle of the speech
4. Previously used arguments appear to be reused and combined into one cohesive message.
In “The Evolution of the Rhetorical Genre of Apologia,” Sharon Downey argues that apologia has undergone significant changes because its function has changed throughout history. Downey takes on a critical generic approach to the feasibility of apologia. Halford Ryan advocates that kategoria and apologia need to be understood as a linked pair. Ryan proposes that a speech of kategoria or accusation motivates a defensive response, which should be treated as a rhetorical speech set.
