KU is most famous for three periods of history - the massive growth during the 1930s, the resistance fight during World War II, and the ideological awakening of the 1980s.

One such incidence, when Copenhagen was plastered with thousands of campaign posters in a single night - is this day commemorated in the official KU song.

This reflected itself in the green uniforms and leather straps members of KU wore and the formation of 'Stormtropperne', a security patrol designed to protect open-air speakers from violent assaults by socialists.

Following the growth of fascism in Europe, Jack Westergaard and his supporters in KU simultaneously lost momentum in the organisation, and were excluded, as the tides - with later party leader Aksel Møller as new chairman - began to change.

KU's young conservatives were therefore among the first to pick up any real resistance, viewing the collaboration policy led by the government as national treason committed by the Social Democrats and the Danish Social Liberal Party, the two parties in government which had disarmed Denmark in the preceding years from being the heaviest armed country in Europe to one of the least militarized in the late 1930s.

To this day KU's legendary 'Konsulentkursus' (KK) (Consultant Course) exists, which albeit in a moderated form works in a similar way, and each year attracts young conservatives who go through a selection procedure.

Due to the chaotic period, it is unfortunately impossible to state the exact number of casualties, but more than 50 KU members are believed to have given their lives in a fight for the freedom of Denmark - more than any other youth organisation during the resistance.

Bjarne Reuter, a popular and much appraised Danish author, has written the bestseller The Boys from St. Petri (Drengene fra Skt.

In the 1980s, as Poul Schlüter became party leader and later prime minister, and inspired by Margaret Thatcher, Ronald Reagan, and the conservative wave sweeping over the Western hemisphere, KU experienced a renaissance in membership.
