council. At its first meeting after the elections, each arrondissement council elects its mayor. Each arrondissement is subdivided administratively into four quartiers. Paris thus has 80 quartiers administratifs, each containing a police station. For a table giving the names of the eighty quartiers, see Quarters of Paris. Arrondissements Notes: 1.

They were numbered from west to east, with the numbers 1–9 situated on the Right Bank of the Seine and the numbers 10–12 on the Left Bank. Each arrondissement was subdivided into four quartiers, which corresponded to the 48 original districts created in 1790. Emperor Napoleon III and the Prefect of the Seine Baron Haussmann developed a plan to incorporate several of the surrounding communes into the Paris jurisdiction in the late 1850s. Parliament passed the necessary legislation in 1859, and the expansion took effect when the law was promulgated on 3 November 1859 (though city taxes were not extended to the new neighborhoods until 1 July 1860). The previous twelve arrondissements were done away with, and twenty new arrondissements were created. In historical records, when it is necessary to distinguish between the two systems, the original arrondissements are indicated by adding the term ancienne ("former" or "old"), for example, 2ème ancienne or 7ème anc. Before the reorganization, non-married couples who lived together were said to have "married at the town hall of the 13th arrondissement" ("se marier à la mairie du 13e arrondissement"), as a jocular reference to there being no 13th. When Haussmann released his plan for the new boundaries and numbering system, residents of Passy objected because it placed them in the new 13th arrondissement. The mayor of Passy, Jean-Frédéric Possoz, devised the idea of a numbering the arrondissements in a spiral pattern beginning on the Right Bank, which put Passy in the 16th. This system turned the Louvre area, which contained the Tuileries Palace and other imperial palaces, into the 1st. The Gobelins area would become the 13th instead. In early 2016, mayor Anne Hidalgo proposed that the first four arrondissements should have their administrations merged, and the Council of Paris approved this
