Pô (department)
Pô  was a department of the French Consulate and of the First French Empire in present-day Italy. It was named after the river Po. It was formed in 1802, when the Subalpine Republic (formerly the mainland portion of the Kingdom of Sardinia) was directly annexed to France. A provisional department called Eridan was planned in 1799 and established in 1801 in the French-occupied Piedmont. After the annexation, Eridan was divided between Po and Doire. Its capital was Turin. The department was disbanded after the defeat of Napoleon in 1814. At the Congress of Vienna, the Savoyard King of Sardinia was restored in all his previous realms and domains, including Piedmont. Its territory is now part of the Italian province of Turin.
