About Anniversary of the Arengo
San Marino marks 25 March as the Anniversary of the Arengo of 1906, paired in the national calendar with the Feast of the Militias.
Official institutional history describes the 25 March 1906 Arengo as the assembly at which family heads chose periodic popular election of the Great and General Council in place of renewal by co-option.
Why Anniversary of the Arengo matters
The anniversary is tied to a constitutional and electoral turning point in San Marino’s political history, while the modern holiday also includes military ceremonial traditions.
The historical assembly and the recurring anniversary are related but distinct: evidence for what happened in 1906 is not automatically evidence for when the annual holiday was formally created.
History of Anniversary of the Arengo
San Marino’s Great and General Council history states that the Arengo of family heads was reconvened on 25 March 1906 after centuries without such a meeting.
At the 1906 assembly, voters chose to replace council renewal by co-option with periodic election, leading to the development of representative electoral government.
Current Republic of San Marino tourism material identifies 25 March as a national holiday commemorating the Arengo of 1906, together with the Feast of the Militias.
