In autumn 1762, the national government in Copenhagen established an extra per capita tax for every person over twelve years, which was later reduced to a charge per household. These extra taxes were intended to help pay loans from foreign governments and to support the price of the Danish-Norwegian currency at the stock market in Hamburg. Strilekrigen took place in Bergen on 18 April 1765, when about 2,000 common people from Nordhordland poured into Bergen to protest against the harsh action of the extra tax. The extra tax had hit the poor farmers and fishermen in rural areas around Bergen particularly hard. The protests, which became violent, were particularly directed at Ulrik Fredrik de Cicignon , the local sheriff  . Rebellions of this magnitude was unprecedented in the 18th century, and officials in Copenhagen were appalled. The authorities send an inquiry north consisting of top officials on a warship. The leaders of the rebellion were indicted by the general court and were convicted of disturbance of public order. The result was that a few farmers ended in prison for life after being pardoned from the death sentence. The extra tax was later abolished in Norway in 1772 but continued in force in Denmark. Ulrik Fredrik de Cicignon sought and received dismissal in May 1766. He moved to Sønderborg in the Duchy of Schleswig.
