National Day in Monaco is also known as Sovereign Prince Day.
The holiday is celebrated on November 19, but the date is chosen by the reigning prince.
The first National Day was celebrated on May 16, 1734, a date chosen by Honore III.
In 1854, Prince Charles III changed the date to November 4 which is the day Patron Saint Charles is celebrated.
In keeping with the tradition, Prince Albert changed the date to November 15 after he began his reign in 1890.
The tradition of changing the date to match the patron saint the prince was named after continued until Prince Albert II took the throne.
He chose to keep the date as November 19, in honour of his father, Prince Ranier III.
The day is designed to celebrate Monaco’s independence as a sovereign nation.
