King Henry V of England is credited with having invented what some consider the first passport in the modern sense, as a means of helping his subjects prove who they were in foreign lands. The earliest reference to these documents is found in the Safe Conducts Act 1414. In 1540, granting travel documents in England became a role of the Privy Council of England, and it was around this time that the term "passport" was introduced. In Scotland, passports were issued by the Scottish Crown and could also issued on the Crown's behalf by burghs, senior churchmen and noblemen. Passports were still signed by the monarch until 1685, when the Secretary of State could sign them instead. The Secretary of State signed all passports in place of the monarch from 1794 onwards, at which time formal records started to be kept; all of these records still exist. Passports were written in Latin or English until 1772, then in French until 1858. Since that time, they have been written in English, with some sections translated into French. In 1855, passports became a standardised document issued solely to British nationals. They were a simple single-sheet hand-drafted paper document.
