Lake Ladoga in the context of "Volkhov River"

The trade route from the Varangians to the Greeks was a medieval trade route that connected Scandinavia, Kievan Rus' and the Eastern Roman Empire. The route allowed merchants along its length to establish a direct prosperous trade with the Empire, and prompted some of them to settle in the territories of present-day Belarus, Russia and Ukraine. The majority of the route comprised a long-distance waterway, including the Baltic Sea, several rivers flowing into the Baltic Sea, and rivers of the Dnieper river system, with portages on the drainage divides. An alternative route was along the Dniester river with stops on the western shore of Black Sea. These more specific sub-routes are sometimes referred to as the Dnieper trade route and Dniester trade route, respectively.

The route began in Scandinavian trading centers such as Birka, Hedeby, and Gotland, the eastern route crossed the Baltic Sea, entered the Gulf of Finland, and followed the Neva River into Lake Ladoga. Then it followed the Volkhov River upstream past the towns of Staraya Ladoga and Novgorod (where it met the Volga trade route and which became a major trade centre), crossed Lake Ilmen, and continued up the Lovat River, the Kunya River and possibly the Serezha River [ru]. From there, a portage led to the Toropa River [ru] and downstream to the Western Dvina River. From the Western Dvina, the ships went upstream along the Kasplya River and were portaged again to the Katynka River (near Katyn), a tributary of the Dnieper. It seems probable that once the route was established, the goods were unloaded onto land transport to cross the portage and reloaded onto other waiting ships on the Dnieper. Along the Dnieper, the route crossed several major rapids and passed through Kiev. After entering the Black Sea, it followed its west coast to Constantinople.

The Rus', also known as Russes, were a people in early medieval Eastern Europe. The scholarly consensus holds that they were originally Norsemen, mainly originating from present-day Sweden, who settled and ruled along the river-routes between the Baltic and the Black Seas from around the 8th to 11th centuries AD.

The two original centres of the Rus' were Ladoga (Aldeigja), founded in the mid-8th century, and Rurikovo Gorodische (Holmr), founded in the mid-9th century. The two settlements were situated at opposite ends of the Volkhov River, between Lake Ilmen and Lake Ladoga, and the Norsemen likely called this territory Gardar. From there, the name of the Rus' was transferred to the Middle Dnieper, and the Rus' then moved eastward to where the Finnic tribes lived and southward to where the Slavs lived.

The Karelian Isthmus (Russian: Карельский перешеек, romanized: Karelsky peresheyek; Finnish: Karjalankannas; Swedish: Karelska näset) is the approximately 45–110-kilometre-wide (30–70 mi) stretch of land situated between the Gulf of Finland and Lake Ladoga in northwestern Russia, to the north of the River Neva. Its northwestern boundary is a line from the Bay of Vyborg to the westernmost point of Lake Ladoga, Pekonlahti. If the Karelian Isthmus is defined as the entire territory of present-day Saint Petersburg and Leningrad Oblast to the north of the Neva and also a tiny part of the Republic of Karelia, the area of the isthmus is about 15,000 km (5,800 sq mi).

The smaller part of the isthmus to the southeast of the old Russia-Finland border is considered historically as Northern Ingria, rather than part of the Karelian Isthmus itself. The rest of the isthmus was historically a part of Finnish Karelia. This was conquered by the Russian Empire during the Great Northern War in 1712 and included within the autonomous Grand Duchy of Finland (1809–1917) of the Russian Empire. When Finland became independent in 1917, the isthmus (except for the territory roughly corresponding to present-day Vsevolozhsky District and some districts of Saint Petersburg) remained Finnish. Finnish Karelia was partly ceded to the Soviet Union by Finland following the Winter War (1939–1940) and Continuation War (1941–1944). In 1940–1941, during the Interim Peace, most of the ceded territories in the isthmus were included within the Karelo-Finnish SSR. However, since World War II the entire isthmus has been divided between the city of Saint Petersburg (mostly Kurortny District), as well as Priozersky District, Vsevolozhsky District and Vyborgsky District of Leningrad Oblast.

Ladoga Karelia (Finnish: Laatokan Karjala, Swedish: Ladogakarelen, Russian: Ладожская Карелия, romanized: Ladožskaja Karelija, Карельское Приладожье, Karelskoje Priladožje or Северное Приладожье, Severnoje Priladožje) is a historical region of Karelia, currently largely in Russia. Today, the term refers to the part of the Republic of Karelia in the Russian Federation comprising the south-west part of the Republic, specifically Lakhdenpokhsky District, Pitkyarantsky District and Sortavala District. This region is on the northern littoral of Lake Ladoga, which borders Olonets Karelia to the East, Leningrad Oblast (Karelian Isthmus) to the south-west and the North Karelia region of Finland to the west.

The Finnic or Baltic Finnic languages constitute a branch of the Uralic language family spoken around the Baltic Sea by the Baltic Finnic peoples. There are around 7 million speakers, who live mainly in Finland and Estonia.

Traditionally, eight Finnic languages have been recognized. The major modern representatives of the family are Finnish and Estonian, the official languages of their respective nation states. The other Finnic languages in the Baltic Sea region are Ingrian and Votic, spoken in Ingria by the Gulf of Finland, and Livonian, once spoken around the Gulf of Riga. Spoken farther northeast are Karelian, Ludic, and Veps, in the region of Lakes Onega and Ladoga.

The Neva (/ˈniːvə/ NEE-və, UK also /ˈneɪvə/ NAY-və; Russian: Нева́, IPA: [nʲɪˈva] ) is a river in northwestern Russia flowing from Lake Ladoga through the western part of Leningrad Oblast (historical region of Ingria) to the Neva Bay of the Gulf of Finland. Despite its modest length of 74 kilometres (46 mi), it is the fourth-largest river in Europe in terms of average discharge (after the Volga, the Danube and the Rhine).

The Neva is the only river flowing from Lake Ladoga. It flows through the city of Saint Petersburg, the three smaller towns of Shlisselburg, Kirovsk and Otradnoye, and dozens of settlements. It is navigable throughout and is part of the Volga–Baltic Waterway and White Sea–Baltic Canal. It is the site of many major historical events, including the Battle of the Neva in 1240 which gave Alexander Nevsky his name, the founding of Saint Petersburg in 1703, and the Siege of Leningrad by the German army during World War II. The river played a vital role in trade between Byzantium and Scandinavia.

The siege of Leningrad was a military blockade undertaken by the Axis powers against the city of Leningrad (present-day Saint Petersburg) in the Soviet Union on the Eastern Front of World War II from 1941 to 1944. Leningrad, the country's second largest city, was besieged by Germany and Finland for 872 days, but never captured. The siege was the most destructive in history and possibly the most deadly, causing an estimated 1.5 million deaths, from a prewar population of 3.2 million. It was not classified as a war crime at the time, but some historians have since classified it as a genocide due to the intentional destruction of the city and the systematic starvation of its civilian population.

In August 1941, Germany's Army Group North reached the suburbs of Leningrad as Finnish forces moved to encircle the city from the north. Land routes from Leningrad to the rest of the Soviet Union were cut on 8 September 1941, beginning the siege. The Germans decided to bomb the city and starve its inhabitants rather than attempt to capture it; many residents starved during the winter of 1941–1942. Supplies were delivered to city by air, by ship over Lake Ladoga, or over the Road of Life, a highway built on the lake when it was frozen. A Red Army offensive opened a narrow land corridor to Leningrad on 18 January 1943, but the siege was not fully broken until 27 January 1944.

Vsevolozhsky District (Russian: Все́воложский райо́н) is an administrative and municipal district (raion), one of the seventeen in Leningrad Oblast, Russia. It is located in the central northwestern part of the oblast on the Karelian Isthmus and borders with Priozersky District in the north, Kirovsky District in the south, Vyborgsky District in the northwest, Nevsky, Krasnogvardeysky, Kalininsky, Vyborgsky, and Kurortny Districts of the federal city of St. Petersburg in the west, and is washed by Lake Ladoga in the east. The area of the district is 3,036.4 square kilometers (1,172.4 sq mi). Its administrative center is the town of Vsevolozhsk. Population (excluding the administrative center): 153,045 (2010 census); 131,233 (2002 Census); 135,318 (1989 Soviet census).

Haukivesi is a lake in southeastern Finland and a part of the Saimaa lake system. Haukivesi is the central basin of the system, collecting 80% of the water that eventually flows into Lake Ladoga through River Vuoksi. Its area is 562.31 square kilometres (217.11 sq mi) (8th). Like other lakes in the system, it has a convoluted shoreline with numerous islands and is divided into a number of smaller regions (selkä) such as Siitinselkä, Saviluoto, Tahkoselkä, Vuoriselkä, Kuokanselkä, Kuivaselkä, Heposelkä, Peonselkä, Tuunaanselkä, Hiekonselkä, Varparannanselkä, and Iso-Haukivesi. Haukivesi stretches from Varkaus to Savonlinna in a northeast–southwest direction. The northern part is shallow, at less than 20 metres (66 ft), but deepens toward the southeast, up to 60 metres (200 ft) at Kuivaselkä.

Most water flows from the east, through Tappuvirta, Oravikoski and Haponlahti locks. A smaller inflow is from the north, through Pirtinvirta in Varkaus. Of the lakes in the Saimaa lake system, Haukivesi receives the most nutrients. The water quality varies with location, because of the differences between the water qualities of the inflows. In Haukivesi, more nutrient-rich water flowing from the north mixes with purer waters from the east. The largest individual pollution sources are the city of Varkaus and its pulp mills, although smaller settlements and diffuse pollution from agriculture and forestry contribute. The lake was heavily polluted by the pulp mills up to the 70s, but stricter regulation forced the mills to treat their wastewaters, and thus the lake recovered.
