The Vistula (Wisła; Weichsel; Visla), is the longest river in Poland at 1,047 km (678 miles) in length. It drains an area of 194,424 km² (75,067 sq. miles), of which 168,699 km² (65,135 sq. miles) lies within Poland (over half the area of the country) .
The Vistula has its source in the south of the country, at Barania Góra (1220 m high) in the Silesian Beskids (western part of Carpathian Mountains) where it starts with the White Little Vistula (Biała Wisełka) and the Black Little Vistula (Czarna Wisełka). It then continues to flow over the vast Polish plains, passing several large Polish cities along its way, including Kraków, Sandomierz, Warsaw, Płock, Włocławek, Toruń, Bydgoszcz, Świecie, Grudziądz, Tczew and Gdańsk. With a delta and several branches (Leniwka, Przekop, Śmiała Wisła, Martwa Wisła, Nogat and Szkarpawa) it empties into the Vistula Lagoon, or directly into the Gdańsk Bay of the Baltic Sea.
In writing about the Vistula River and its peoples, Ptolemy uses the Greek spelling, "Ouistoula". Other ancient sources spell it "Istula". Pomponius Mela refers to the "Visula" (Book 3) and Ammianus Marcellinus to the "Bisula" (Book 22), both of which names lack the -t-. The definitive reference is probably Jordanes (Getica 5 & 17), who uses "Viscla". The Anglo-Saxon poem Widsith refers to it as the "Wistla".
For centuries, the river was well-known in Germany and surrounding countries by the German name Weichsel (in medieval German documents spelled Wissel, Wixel etc.). The most recent glaciations of the Pleistocene epoch, which ended around 10,000 BCE, is called Weichsel glaciation in regard to northern central Europe.
Ptolemy, in the second century AD, would write of the Vistula as the border between Germania and Sarmatia. To the east of the Vistula were found Baltic-speaking tribes, generally identified with the historical Aestians: Galindians, Sudovians and Borusci. It has not been verified whether any Slavic tribes were settled along the Vistula at that time.
Tacitus is another source regarding information on the early inhabitants of the Vistula. However, he makes no secret that many of the tribes to the east of the Vistula were somewhat shrouded in mystery. For example, when describing the Venethi, Peucini and Fenni he wrote that he was not sure if he should call them Germans, since they had settlements and they fought on foot, or rather Sarmats since they have some similar customs to them.
The Vistula river used to be connected to the Dnieper River, and thence to the Black Sea. The Baltic-Sea--Vistula--Dnieper--Black-Sea water route was one of the most ancient trade-routes, the Amber Road, on which amber and other items were traded from Northern Europe to Greece, Asia, Egypt, and elsewhere.
The Second World war was sparked by conflict over the mouth of the Vistula. The formerly-German city of Danzig (today Gdańsk) lies at the mouth of the river, where the Vistula meets the Baltic. German desire to fully incorporate that city into Germany thus connecting East Prussia to the rest of Germany, and Polish designs on the city to give them a seaport, sparked the outbreak of war in September 1939.
The Upper Vistula changed hands from time to time, but after the emergence of Poland in 966, became solidly Polish (Slavic) territory. The past two millennia saw Germanics pushing east and south along the Vistula as the Slavs pushed north and west, with neither ever attaining sustained domination over the entire river basin. This was changed after the postwar expulsions of Germans from the area by Stalin.
In 1945, the victorious Stalin changed the longstanding Germanic-Slavic balance of the Vistula Basin by means of ethnic cleansing (a tactic employed by the Soviet Union across their empire). In 1945, all Germans from the Vistula basin (along with those in East Prussia and the Oder basin) were expelled from their homes, and their property seized. Ever since 1945, the entire Vistula basin has thus been Polish-dominated territory for the first time in history.
Today, the Vistula is part of the Polish heartland, a far cry from being "the eastern reaches of Germany/germania" as it had been since the Iron Age. The eastern border of Germany was shifted west by Stalin to the artificial Oder-Neisse Line.
The Vistula is navigable, but large parts of its course do not meet the requirements of modern inland navigation. From the Baltic Sea to Bydgoszcz (where the Bydgoszcz Canal connects to the river), Vistula can accommodate modest river vessels of CEMT class II. Further upstream the river does not have enough depth to allow river barges to navigate.
Upstream of Warsaw, a project was undertaken to enlarge the capacity of the river by building a number of locks in Cracow area; this project was never prolonged further downstream, so that the navigability of the Vistula remains problematic. The potential of the river in the decades to come would increase considerably if a restoration of the East-West connection via the Narew - Bug - Mukhovets - Pripyat - Dnieper waterways would be considered. The shifting economic importance parts of Europe may make this option interesting.
