Between 1881 and 1937, these conventions fostered a national feeling among Acadians in all three Maritime provinces. Organized by the Société nationale l'Assomption, they promoted Acadian influence in the Church and education, championed the use of the French language, encouraged development in agriculture and economy as well as settlement. The first convention, at Memramcook in 1881, chose August 15 as the national holiday. The second, held at Miscouche in 1884, adopted the distinctive flag and the anthem, Ave Maris Stella, which have become enduring symbols of Acadian identity.
