Many emblematic – and sometimes stereotyped – figures bear witness to voyages (and sometimes long-lost communities). These include pilgrims and members of religious orders in the Middle Ages, merchants (16th-17th c.), scholars, dragomen, students (early 19th century), political exiles (late 19th century), lawyers dealing with the Armenian issue, artists (starting in the 19th c.) soldiers volunteering for the First World War, refugees, and members of the Resistance in World War II (including Missak Manouchian, a hero of the infamous "Red Poster") – some of them witnesses to success and integration, and some who are forgotten.
