The Daugava is considered the Latvian national river. The Daugava is the largest river that flows through Latvia (total length 1005 km, of these 352 km flow through Latvian territory).

Known as the "river of fate" or "mother of rivers", the Daugava has served as an ancient trade route linking the Baltic Sea to the Black Sea, profoundly influencing the flow of Latvian history. For centuries the Daugava has served as an essential transport artery, means of livelihood, and source of energy. (Latvia's hydroelectric stations are located along the Daugava). Today, as in the past, the Daugava serves as a borderline between distinct Latvian cultural and historical regions, separating Kurzeme and Zemgale from Vidzeme and Latgale.
