Taking the ‘Fridays for Future’ movement as its starting point, this article conceptualizes and defends youth disobedience, understood as principled disobedience by legal minors. The article first argues that the school strike for climate can be viewed as civil disobedience. Then, the article distinguishes between various forms of youth disobedience (according to whether they involve child-specific issues or actions). Building on the democratic rationale for civil disobedience, the remainder of the article argues that there is a special justification for youth (...) disobedience. To show this, it argues that children are wrongfully excluded from political participation and that principled law-breaking can be an important remedy to this exclusion. The upshot is that adults should engage seriously and leniently with youth disobedience. (shrink)
