Sweden has a history of strong political involvement by ordinary people through its "popular movements" (''Folkrörelser''), the most notable being trade unions, the independent Christian movement, the temperance movement, the women's movement, and the intellectual property pirate movements. Sweden was the first country in the world to outlaw corporal punishment of children by their parents (parents' right to spank their own children was first removed in 1966, and it was explicitly prohibited by law from July 1979).
