Sápmi is the cultural region traditionally inhabited by the Sámi people. Sápmi includes the northern parts of Fennoscandia, stretching over four countries: Norway, Sweden, Finland, and Russia. Most of Sápmi lies north of the Arctic Circle, bounded by the Barents Sea, Norwegian Sea, and White Sea. In the south, Sápmi extends to the counties of Trøndelag in Norway and Jämtland in Sweden.

Jämtland (Swedish: [ˈjɛ̌mːtland] ) is a historical province (landskap) in the centre of Sweden in northern Europe. It borders Härjedalen and Medelpad to the south, Ångermanland to the east, Lapland to the north and Trøndelag and Norway to the west. Jämtland covers an area of 34,009 square kilometres, 8.3% of Sweden's total area and is the second largest province in Sweden. It has a population of 115,331, the majority of whom live in Storsjöbygden, the area surrounding lake Storsjön. Östersund is Jämtland's only city and is the 24th most populous city in Sweden. The historical province is one of the least densely populated.

Jämtland was originally an autonomous republic, its own nation with its own law, currency and parliament. Jämtland was conquered by Norway in 1178 and stayed Norwegian for over 450 years until it was ceded to Sweden in 1645. The province has since been Swedish for roughly 370 years, though the population did not gain Swedish citizenship until 1699. The province's identity is manifested with the humorous culture and marketing concept of a republic within the kingdom of Sweden, although this is only done semi-seriously.

Helgeland is the most southerly district in Northern Norway. Generally speaking, Helgeland refers to the part of Nordland county that is located south of the Arctic Circle. It is bordered in the north by the Saltfjellet mountains and Svartisen glacier, which form a natural border with the Salten district. In the south, Helgeland borders Trøndelag county.

The district covers an area of about 18,832 square kilometres (7,271 sq mi), with nearly 79,000 inhabitants. There are four towns in the district: from south to north these are Brønnøysund, Mosjøen, Sandnessjøen, and Mo i Rana.

Innlandet is a county in Norway. It was created on 1 January 2020 with the merger of the old counties of Oppland and Hedmark (Jevnaker Municipality and Lunner Municipality were transferred to the neighboring county of Viken on the same date). The new county has an area of 52,113 square kilometres (20,121 sq mi), making it the largest county in Norway after the division of the old Troms og Finnmark county in 2024.

The region was known as Opplandene or Opplanda since the middle ages. Historically part of Akershus, Oplandene County existed from 1757 to 1781, when it was divided into Christians County and Hedemarken County, also known as Western and Eastern Oplandene. In 1919 the two counties were renamed Oppland and Hedmark, and in 2020 they were again merged under the name Innlandet (with the exception of Jevnaker Municipality and Lunner Municipality, which went to the new county of Viken). This present name is a newly constructed name with no historical basis as a subdivision name and was recommended not to be used by the Norwegian Language Council. It translates to "The Inland". The county covers approximately 17% of the total area of the mainland area of Norway. It stretches from Akershus, Buskerud, and the Oslo region in the south to Trøndelag county in the north. In the northwest, the county borders Møre og Romsdal and the Vestland county in the west. To the east the county borders the Swedish counties of Jämtland, Värmland and Dalarna.

Nordland (Norwegian pronunciation: [ˈnûːrlɑn] ; Lule Sami: Nordlánnda, Southern Sami: Nordlaante, Northern Sami: Nordlánda, lit. 'Northland') is one of the three northernmost counties in Norway in the Northern Norway region, bordering Troms in the north, Trøndelag in the south, Norrbotten County in Sweden to the east, Västerbotten County to the south-east, and the Atlantic Ocean (Norwegian Sea) to the west. The county was formerly known as Nordlandene amt. The county administration is in the town of Bodø. The remote Arctic island of Jan Mayen has been administered from Nordland since 1995. In the southern part of the county is Vega, listed on the UNESCO World Heritage Site list.

Trondheim (UK: /ˈtrɒn(d)haɪm/ TRON(D)-hyme, US: /ˈtrɒnheɪm/ TRON-haym; Urban East Norwegian: [ˈtrɔ̂nː(h)æɪm]; Southern Sami: Tråante), historically Kaupangen, Nidaros, and Trondhjem (locally [ˈtrɔ̂nːjæm] ), is a city and municipality in Trøndelag county, Norway. As of 2025, it had a population of 216,518. Trondheim is the third most populous municipality in Norway, and is the fourth largest urban area. Trondheim lies on the south shore of Trondheim Fjord at the mouth of the River Nidelva. Among the significant technology-oriented institutions headquartered in Trondheim are the Norwegian University of Science and Technology (NTNU), the Foundation for Scientific and Industrial Research (SINTEF), the Geological Survey of Norway (NGU), and St. Olavs University Hospital.

The settlement was founded in 997 as a trading post and served as the capital of Norway through the Viking Age until 1217. From 1152 to 1537, the city was the seat of the Catholic Archdiocese of Nidaros; it then became, and has remained, the seat of the Lutheran Diocese of Nidaros and the site of the Nidaros Cathedral. The city was incorporated in 1838. The current municipality was formed in 1964, when Trondheim merged with Byneset Municipality, Leinstrand Municipality, Strinda Municipality, and Tiller Municipality, and further expanded on 1 January 2020, when Trondheim merged with Klæbu Municipality.

Erik Hakonsson, also known as Eric of Hlathir or Eric of Norway (Old Norse: Eiríkr Hákonarson; 960s – 1020s), was Earl of Lade, Governor of Norway and Earl of Northumbria. He was the son of Earl Hákon Sigurðarson and brother of the legendary Aud Haakonsdottir of Lade. He participated in the Battle of Hjörungavágr, the Battle of Svolder and the conquest of England by King Canute the Great.

The Earls of Lade (Norwegian: ladejarler) were a dynasty of Norse jarls who ruled what is now Trøndelag and Hålogaland from the 9th century to the 11th century.

The seat of the Earls of Lade was at Lade Gaard (Old Norse: Hlaðir), now located in the eastern parts of the city of Trondheim. The site is near the seaside of the Trondheimsfjord, which was an important waterway in the Viking Age.

The Trondheim Fjord or Trondheimsfjorden (pronounced [ˈtrɔ̂nː(h)æɪmsˌfjuːɳ]), an inlet of the Norwegian Sea, is Norway's third-longest fjord at 130 kilometres (81 mi) long. It is located in the west-central part of the country in Trøndelag county, and it stretches from Ørland Municipality in the west to Steinkjer Municipality in the north, passing the city of Trondheim on its way. Its maximum depth is 617 metres (2,024 ft), in the channel between Orkland Municipality and Indre Fosen Municipality.

The largest islands in the fjord are Ytterøya and Tautra; the small island of Munkholmen is located near the harbor of Trondheim; and there are several islands at the entrance of the fjord. The narrow Skarnsundet is crossed by the Skarnsund Bridge. The part of the fjord to the north of the strait is referred to as the Beitstadfjorden. The main part of the Trondheimsfjord is ice-free all year; only Verrasundet, a long and narrow fjord branch in the northern part of the fjord, might be ice covered in winter. The Beitstadfjorden might also freeze over in winter, but only for a few weeks.
