National Holiday (Staatsfeiertag)

The date August 15 was chosen for two reasons: it is the Feast of the Assumption of Mary, which has deep roots in Catholic Liechtenstein, and it marks the 1906 birth of Prince Franz Joseph II, who reigned from 1938 to 1989. The holiday was officially established in 1940 by Prince Franz Joseph II himself, who wanted to strengthen national unity during World War II. Before that, August 15 was solely a religious feast. The prince's birthday had been celebrated separately since the 19th century, but its combination with the Assumption made it a unique double celebration. The holiday was initially called 'Prince's Birthday' and later renamed 'National Holiday' in the 1990s, though the date remained unchanged.

The festivities begin with a morning church service in the capital, Vaduz, followed by an official state ceremony at the Schlossplatz (castle square) in front of Vaduz Castle. The Prince or a member of the princely family gives a speech that is broadcast nationwide. In the afternoon, a 'Bürgerfest' (citizens' party) takes place with food stalls, music, and entertainment. Traditional dishes include 'Käsknöpfle' (cheese dumplings), 'Rösti', and sausages. In the evening, a grand fireworks display lights up the sky above Vaduz Castle. Many residents also attend local community events, such as street festivals, concerts, and sports competitions. The holiday is a public day off for all citizens, and it is common for families and friends to gather for barbecues and picnics.

The National Holiday is Liechtenstein's most important secular celebration, symbolizing national unity and pride. It honors the principality's sovereignty, its princely family, and its Catholic heritage. The day also serves as a reminder of Liechtenstein's unique history as a small, independent state that has maintained its identity through centuries. It is a moment for citizens to reflect on their shared values, traditions, and the enduring role of the monarchy in modern Liechtenstein society.
