In 1800 the arrondissement of Paris was established as part of the department Seine. In 1962 it absorbed the communes of the former arrondissements of Saint-Denis and Sceaux. In 1964 and 1966 it lost territory to the new arrondissements of Bobigny, Créteil, Nanterre, Antony and Nogent-sur-Marne. In 1968 the department Seine was disbanded, and the arrondissement of Paris became the single arrondissement of the department of Paris.[4]
