The World’s First Passports

  During World War I, European governments introduced border passport requirements for security reasons, and to control the emigration of people with useful skills. These controls remained in place after the war, becoming a standard, though controversial, procedure. British tourists of the 1920s complained, especially about attached photographs and physical descriptions, which they considered led to a "nasty dehumanisation". The British Nationality and Status of Aliens Act was passed in 1914, clearly defining the notions of citizenship and creating a booklet form of the passport.
