History

The arrondissement of Pontoise was created in 1800 as part of the department Seine-et-Oise.^[4] In 1968 it became part of the new department Val-d'Oise.^[5] At the January 2017 reorganisation of the arrondissements of Val-d'Oise, it received one commune from the arrondissement of Sarcelles, and it lost 10 communes to the arrondissement of Argenteuil and two communes to the arrondissement of Sarcelles.^[6]
