The 23 February 2005 French law on colonialism was an act passed by the National Assembly, which imposed on high-school (lycée) teachers a requirement to teach the "positive values" of colonialism to their students (Article 4, Paragraph 2). The law, particularly the aforementioned paragraph and Articles 1 and 13, created a public uproar and drew massive opposition from the left, and Article 4, Paragraph 2 was repealed by president Jacques Chirac (UMP) at the beginning of 2006, after accusations of historical revisionism from various teachers and historians, including Pierre Vidal-Naquet, Claude Liauzu, Olivier Le Cour Grandmaison and Benjamin Stora. Its Article 13 was also criticized as it supported former Organisation armée secrète (OAS) militants.
