Victory Day is observed in Tunisia every June 1, commemorating the adoption of the Constitution of Tunisia in 1959. This official flag day requires the Tunisian flag to be flown on all public buildings. The origins of this celebration can be traced back to Tunisia's history as a province of the Ottoman Empire and its subsequent transition to a French protectorate in 1881, which sparked a nationalist movement. The push for independence culminated in Tunisia achieving sovereignty from France in 1956, followed by the establishment of a constitutional republic in 1959. The day serves as a reminder of Tunisia's journey towards democracy and national identity.
