Republic Day is observed in the canton of Neuchâtel, Switzerland, every March 1. This day commemorates the 1848 revolution that led to Neuchâtel becoming a republic, marking a significant shift from its previous status as a principality under various dynasties. Initially, Neuchâtel was part of the Prussian monarchy until it joined the Swiss Confederation in 1815 as a unique monarchy among republican cantons. The republic's establishment followed a peaceful revolution, and the Prussian claim to Neuchâtel was relinquished in 1857 after the Neuchâtel Crisis. The celebration serves as a reminder of the canton’s transition to a republican form of government and its integration into the Swiss Confederation.
