Named after the town of Boulogne-Billancourt and the boulevard Jean-Jaurès.
Boulogne takes its name from Boulogne-sur-Mer: its parish was created in 1330 for Marian pilgrimages closer to Paris than those of the northern town; the name Boulogne-Billancourt dates from 1926. The boulevard, first called boulevard de Strasbourg after the annexation of Alsace-Lorraine, honours Jean Jaurès (1859–1914), the socialist orator assassinated on the eve of the First World War, which he opposed.
