Liechtenstein document photos online

In 1866 Liechtenstein sent 80 soldiers to guard an Alpine pass during the Austro-Prussian War; they never fired a shot, but the country's legend insists they came home 81 strong, having picked up a friendly Austrian liaison officer along the way. It was the army's last march. Two years later, on 12 February 1868, the principality disbanded its forces for good and declared permanent neutrality. Today this doubly landlocked microstate has no army and no airport, yet its citizens hold one of the planet's most travel-friendly passports and quietly run a global empire in an unlikely export: false teeth.

• Passport power The Liechtenstein passport ranks among the world's strongest, granting visa-free or visa-on-arrival access to roughly 180 destinations on the Henley Passport Index.
• Travel ID Liechtenstein nationals can cross into every EU state, fellow EFTA countries and many Balkan neighbours using just their national identity card instead of a passport.
• Currency Liechtenstein has used the Swiss franc as legal tender since 1920 under a monetary union with Switzerland, making it one of Europe's last 'franc' economies outside the euro.
• Banknotes The principality has never printed its own circulating banknotes, except for three emergency heller issues in 1920, and today mints only collector commemorative coins under a 1980 treaty with Switzerland.
• Citizenship Ordinary naturalisation can require a public vote by the residents of your own municipality, one of the world's most restrictive paths to a passport, or simply 30 years of residence by right.
• Statehood Liechtenstein became fully sovereign on 23 August 1866 when the German Confederation dissolved, yet it waited until 1990 to join the United Nations as the 160th member state.
• Geography It is one of only two doubly landlocked countries on Earth, ringed entirely by landlocked Switzerland and Austria, the other being Uzbekistan.
• Industry The town of Schaan hosts Ivoclar Vivadent, the world's leading maker of artificial teeth, producing tens of millions of dentures a year and accounting for a large share of the global market.
• Military After its 80-strong army marched home in 1866, Liechtenstein abolished its military in 1868 and has not maintained a standing army since.
