Many women in history have presented themselves as men in order to advance in typically male-dominated fields. There are many documented cases of this in the military during the American Civil War.[21] However, their purpose was rarely for fraudulent gain. They are listed in the List of wartime cross-dressers.
Spies have often pretended to be people other than they were. One famous case was that of Chevalier d'Eon (1728–1810), a French diplomat who successfully infiltrated the court of Empress Elizabeth of Russia by presenting as a woman.
Historically, when military record-keeping was less accurate than today, some persons—primarily men—falsely claimed to be war veterans to obtain military pensions.
