Sartrouville is a commune in the Yvelines department in the Île-de-France in north-central France. it is located in the north-western suburbs of Paris 17.1 km (10.6 mi) from the center.

In the Middle Ages the name Sartrouville was recorded in Medieval Latin as Sartoris Villa. The origin and meaning of Sartoris Villa is still debated. Some think the name comes from the Roman patronym Saturus (probably a Gallo-Roman landowner) and means "estate (villa) of Saturus". Others believe that the word sartoris comes from the Medieval Latin past participle exsartum ("cleared for cultivation"), from Latin sartum ("hoed"), and means "estate of the land-clearers", probably in reference to the deforestation that took place around Sartrouville in Antiquity or in the Early Middle Ages to enable the cultivation of the land.

Sartrouville is served by Sartrouville station on Paris RER line A and on the Transilien Paris – Saint-Lazare suburban rail line.

Jean Léon Jaurès (French pronunciation: [ʒɑ̃ ʒɔ.ʁɛs]; full name Auguste Marie Joseph Jean Léon Jaurès; 3 September 1859 – 31 July 1914) was a French Socialist leader. Initially an Opportunist Republican, he evolved into one of the first social democrats, becoming the leader, in 1902, of the French Socialist Party, which opposed Jules Guesde's revolutionary Socialist Party of France. The two parties merged in 1905 in the French Section of the Workers' International (SFIO). An antimilitarist, Jaurès was assassinated at the outbreak of World War I, and remains one of the main historical figures of the French Left.

The son of an unsuccessful businessman and farmer, Jean Jaurès was born in Castres (Tarn), in a modest French provincial bourgeois family. He was the first cousin once removed of the admiral and senator Benjamin Jaurès, who was named Minister of the Navy and Colonies in 1889, and of the admiral Charles Jaurès. His younger brother, Louis, also became an admiral and a Republican-Socialist deputy.
