There are a few potential interpretations of your question:
* The historical movement for Savoy's independence: The desire for independence from both France and Italy has existed for centuries, with peaks during periods of political instability like the Napoleonic wars or World War I. There's no single founding date for this sentiment, as it evolved over time.
* Modern political parties or groups advocating for Savoy: Several groups today advocate for greater autonomy or independence for Savoy, but these groups emerged in the 20th and 21st centuries, and their specific founding dates vary. Examples include:
* Mouvement pour la Savoie (MPS): Founded in 1984.
* Comité Régional d'Action Savoyarde (CRAS): Founded in 1993.
* Parti Savoyard : Founded in 1999.
Therefore, to answer your question accurately, you need to specify which specific organization or movement you're interested in.
