Editing Val-d'Oise (section)

==History==
The original departments of France were established in 1790 when the French National Assembly split the country into 83 departments of roughly the same size and population. They were designed as sets of communes, and when better maps became available, certain revisions had to be made. 
In 1964, it was determined to divide up the departments of [[Seine (department)|Seine]] and [[Seine-et-Oise]]. Val-d'Oise was one of the new departments so formed, and was created entirely from the previous department of Seine-et-Oise.<ref>{{cite book |author=Gwillim Law |title=Administrative Subdivisions of Countries: A Comprehensive World Reference, 1900 through 1998 |url=https://books.google.com/books?id=nXCeCQAAQBAJ&pg=PA132 |year=1999 |publisher=McFarland |isbn=978-1-4766-0447-3 |pages=132–133}}</ref>
