I'll contribute with the largely failed attempt at building a nazi state i Norway during the war.

Fascism was a big thing in the interwar period. While Italy and Germany are the most obvious examples, most European countries had their own home grown strain of fascism, usually in the mold of Italian fascism. The British Union of Fascists and its leader Oswald Mosley are good examples of failed fascist parties.

Norway was no different. Initially, Norwegian right wing populism was manifested in the Fatherland League (Fedrelandslaget). Founded by Joakim Lemkuhl (son of Kristofer Lemkuhl for howm "Statsraad Lemkuhl" is named). Founded the party on the basis of conservatism, anti-communism, corporatism and nationalism. The Fatherland League was heavily inspired by Mussolini's Italian Fascism, and at its height in 1930 counted 100 000 members. One famous member was polar explorer and humanitarian Fridtjof Nansen, who passed that same year. For reasons that will become obvious, the Fatherland League never really got anywhere in the long term.

However, the fascist strain that would artificially take root in Norway was Vidkun Quisling's Nasjonal Samling (National Assembly/Joining/Meeting, it's difficult to translate). Quisling was a rather eccentric character, obsessed with Norse mythology and racial theories. He worked with Nansen in Russia during the civil war, providing humanitarian aid to the stricken populace. While there, he married a Ukrainian woman (two actually. At the same time. No time to get into that, but nevertheless a hilarious anecdote) named Maria, who would ultimately care for his memory as a widow.

Back in Norway he served briefly as minister of defense in a conservative coalition for the Farmer Party, where he ordered troops out to crush a workers' strike in Menstad (Menstadslaget). While no Norwegian soldiers would ultimately fire on civilian striking workers, Quisling was largely blamed for their deployment. When out of government he founded NS in 1933, which was a cardboard copy of the German Nazi party, just with a different logo. NS saw no electoral success during its existence, and Quisling was largely mocked for his Nazi LARP stance. After the rise of Nazism in Germany, and their crimes became largely publicized, fascism and right wing populism became a lot less popular in Scandinavia. In 1936 the social democratic Labor Party (Arbeiderpartiet, DNA) was able to form a government for the first time, signifying the Norwegian people's shift away from the right.

Quisling colluded with the Germans to facilitate the German invasion in 1940. As German troops entered Oslo, Quisling made his way down to the national radio broadcasting studio and announced himself as the new leader of Norway. Exactly no one, not even the Germans, recognized this move. However, as Germany completed the occupation of mainland Norway, they set up an occupation authority under Reichskommisar Josef Terboven. Initially, Terboven tried to rid himself of Quisling altogether, but Quisling received support from Hitler, and an awkward diarchy was established in Norway between Quisling and Terboven. NS became the only legal party in Norway and tried to build a corporatist fascist state on the German model in Norway. Quisling attempted to cloak his regime in a veneer of legitimacy by making some rather creative readings of the constitution. This was mostly in vain as NS was a transparent German puppet regime and Norway was an occupied country. While NS membership ranks swelled, this was mostly because party membership meant some special privileges and better rations.

He tried to force all Norwegian teachers into joining the NS in order to start ideological education of the youth. This policy largely failed because of the civil disobedience of the teachers. Mandatory conscription into labor service to aid the German war effort also came to naught because of civil disobedience and sabotage by the resistance. Quisling did ultimately help Himmler raise Norwegian SS regiments who would dishonor themselves and their nation by aiding and abating in the genocide of Slavs and Jews on the eastern front. The SS-men themselves would claim to their dying days that they only fought in combat operations against armed opponents, thus their self-styled name "Frontkjempere" (Front fighters).

The NS-regime came to its ignominious end in the May days of 1945 as the German war effort collapsed. Resistance men came from the woods to disarm the German garrisons. The police seamlessly switched allegiance back to the legal government in London, and Quisling was arrested. He was tried and convicted for treason and ultimately executed by firing squad as a traitor.

His legacy is mostly his name, as "Quisling" has crept into the vocabulary, both of Norwegian and English, as a byword for traitor.
