Since 1814 Sweden has avoided involvement in armed conflicts and carried out policies of non-alignment in peacetime and neutrality during war. Even though the Swedish government often describes Sweden as a ‘nation of peace’, in 2004 the 200-year anniversary of that peace passed by with barely any attention. Despite its extraordinary longevity, research about the Swedish experience of enduring peace is underdeveloped. 200 Years of Peace places this long period of peace in broader academic and public discussions surrounding claimed Swedish exceptionality as it is represented in the nation’s social policies, expansive welfare state, eugenics, gender equality programs, and peace.
