What is "tanaro"

The Tanaro , known as Tanarus in ancient times and Tane or Tani in piedmontese language, is a long river in northwestern Italy.

It begins in the Ligurian Alps, near the border with France, and is the most significant right-side tributary to the Po in terms of length, size of drainage basin (partly Alpine, partly Apennine), and discharge. At its confluence with Po, it is longer by about than the upper Po, a case similar to the famous Missouri tributary being longer than Mississippi in the United States.

Tanaro was a short-lived department of the French Consulate and of the First French Empire in present-day Italy. It was named after the river Tanaro. It was formed in 1802, when the Subalpine Republic (formerly the mainland portion of the Kingdom of Sardinia) was directly annexed to France. Its capital was Asti.

The department was disbanded in 1805, when the French conquered the Ligurian Republic, and its territory was divided over the departments of Marengo, Montenotte and Stura.
