King Henry V of England is said to have invented the first passport as a means of helping his subjects prove who they were in foreign lands. The earliest reference to these documents is found in a 1414 Act of Parliament.
Today, your passport is your entry into foreign countries as a tourist, student or worker.
Yet not all passports are created equally.
The Henley Passport Index is a ranking of the world’s passports according to the number of destinations their holders can access without a visa. The rankings are based on data provided by the International Air Transport Association (IATA), which has the world’s largest and most accurate database of travel information.
