The first Norwegian Manifesto (Manifesto-I) Against Bullying was launched by the Prime Minister in autumn 2002 and lasted for 2 years. A background for Manifesto-I was that school bullying had increased almost linearly in Norway with over 60% more victims and bullies since 1995. During the manifest period, the percentage of victims and bullies were reduced. After that period, from 2004 to 2008, the percentage of victims and bullies increased again, although a second manifesto (Manifesto-II) was launched by a new government in January 2006. The changes for both victims and bullies were significant. Preconditions for the success of the Manifesto-I and the activities comprising it are described, analysed, and compared with the Manifesto-II period. (Contains 5 tables.)
