The National Socialist Movement in the Netherlands (Dutch: Nationaal-Socialistische Beweging in Nederland, pronounced [nɑ(t)ɕoːˌnaːlsoːɕaːˈlɪstisə bəˈʋeːɣɪŋ ɪn ˈneːdərlɑnt]; NSB) was a Dutch fascist and later Nazi political organisation that eventually became a political party. As a parliamentary party participating in legislative elections, the NSB had some success during the 1930s. Under German occupation, it remained the only legal party in the Netherlands during most of the Second World War. Source: Wikipedia (en)
