Dino Knudsen investigates how the American trade union movement, including figures such as Jay Lovestone and Irving Brown, established anti-Communist networks among the Nordic Non-Communist Left during the early Cold War. What were the implications of these networks, in the context of the Marshall Plan, for the Nordic trade unions in following their British and American colleagues in breaking with the World Federation of Trade Unions and establishing the International Confederation of Free Trade Unions? In Denmark, American authorities came to function as a kind of mediator between labor and capital, sanctioning a class compromise between them, and contributing to stabilize and maintain a social democratic hegemony in the labor movement.
