About Lateran Treaty Day in Vatican City
The day commemorates the Lateran Treaty, the agreement that resolved the “Roman Question” and gave Vatican City its modern legal status as a sovereign state. For Vatican City, the holiday is tied to the city-state’s own constitutional identity rather than to a wider national historical event. Its practical importance is therefore specific to Vatican institutions and the small local community, where the date is recognized as an official public holiday. It also falls on the same date as the Catholic feast of Our Lady of Lourdes, but that religious observance is distinct from the civic holiday itself.
History
The Lateran Treaty was signed in 1929 between the Holy See and the Kingdom of Italy. It recognized the sovereignty of Vatican City and defined the relationship between the Holy See and Italy after the loss of the Papal States in the 19th century.
Traditions
There are no widely documented public traditions specific to Vatican City for Lateran Treaty Day beyond its formal commemorative character as an official holiday.
