Most visits to Liechtenstein are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
Liechtenstein is a principality governed under a constitutional monarchy. It has a form of mixed constitution in which political power is shared by the monarch and a democratically elected parliament. There is a multi-party system and a form of representative democracy in which the prime minister and head of government is responsible to parliament. However the Prince of Liechenstein is head of state and exercises considerable political powers.
Liechtenstein is the smallest yet the richest (by measure of GDP per capita) German-speaking country in the world and the only country to lie entirely within the Alps.
