Un Canadien errant: "Un Canadien errant" ("A Wandering Canadian") is a song written in 1842 by Antoine Gérin-Lajoie after the Lower Canada Rebellion of 1837–38.  Some of the rebels were condemned to death, others forced into exile to the United States and as far as Australia.  Gérin-Lajoie wrote the song, about the pain of exile, while taking his classical exams at the Séminaire de Nicolet.  The song has become a patriotic anthem for certain groups of Canadians who have at a point in their history experienced the pain of exile.  In addition to those exiled following the Lower Canada Rebellion, it has come to hold particular importance for the rebels of the Upper Canada Rebellion, and for the Acadians, who suffered mass deportation from their homeland in the Great Upheaval between 1755 and 1763.  The Acadian version is known as "Un Acadien errant."

World War II evacuation and expulsion: Mass evacuation, forced displacement, expulsion, and deportation of millions of people took place across most countries involved in World War II.  A number of these phenomena were categorised as violations of fundamental human values and norms by the Nuremberg Tribunal after the war ended.  The mass movement of people – most of them refugees – has either been caused by the hostilities, or enforced by the former Axis and the Allied powers based on ideologies of race and ethnicity, culminating in the postwar border changes enacted by the international settlements.  The refugee crisis created across formerly occupied territories in World War II provided the context for much of the new international refugee and global human rights architecture existing today.

Deportation of Azerbaijanis from Armenia: The deportation of Azerbaijanis from Armenia took place as an act of forced resettlement and ethnic cleansing throughout the 20th century.
