Alta Dam controversy

In 1978, the Norwegian government decided to build a hydroelectric power station at Alta in the north of Norway. This saw the construction of a dam is a barrier that restricts or stops water and can provide water for consumption and industrial use. Water can also be used to create a renewable (not relying on fossil fuels like coal and oil) and eco-friendly source of energy which why they built a power station to go along with it. However, it was controversial because the building of the dam would put a Sámi village underwater as well as disrupt nature like a herding ground for reindeer.
The Sámi are a group of Finno-Ugric people who are indigenous to the region of Sápmi which is in the north of Scandinavia encompassing of Norway, Sweden and Finland's mainland borders. You may know the region as its other name Lapland as one of Santa Claus' homes but the Sámi prefer if you don't say Lapp and instead say Sápmi.
The controversy inspired the longest civil disobedience in Norwegian history. For the first time since World War 2, Norwegians were arrested and charged with violating laws against rioting. At one point the government sent 10% of the country's police force to Alta to remove protestors from the construction site. Especially the Sámi people to involved, trying to protect their land and their culture. The central organisations for the Sámi people discontinued all cooperation with the Norwegian government. Two Sámi women even travelled to Rome to petition the Pope. In the end, the village was spared but the dame was built.
The dam in Frozen 2 was inspired by this controversial dam.
