DUEL


As practised from the 11th to 20th centuries in Western societies, a duel is
an engagement in combat between two individuals, with matched weapons in
accordance with their combat doctrines. In the modern application the term
is applied to air combat between fighter pilots.

The Romanticism depiction of medieval duels was based on either a pretext of
defence of honor, usually accompanied by a trusted representative (who might
themselves fight), often in contravention of the duelling conventions, or as
a matter of challenge of the champion which developed out of the desire of
one party (the challenger) to redress a perceived insult to his or his
sovereign's honor. The goal of the honourable duel was often not so much to
kill the opponent as to gain "satisfaction", that is, to restore one's honor
by demonstrating a willingness to risk one's life for it.
