The March 1949 Syrian coup d'état was a bloodless coup d'état that took place on 30 March, and was the first military coup in modern Syrian history which overthrew the country's democratically elected government.
 It was led by the Syrian Army chief of staff, Husni al-Za'im, who became President of Syria on 11 April 1949.
 Among the officers that assisted al-Za'im's takeover were Adib al-Shishakli and Sami al-Hinnawi, both of whom would later also become military leaders of the country.
 The president, Shukri al-Quwatli, was accused of purchasing inferior arms for the Syrian Army and of poor leadership.
 He was briefly imprisoned, but then released into exile in Egypt.
 Syria's legislature, then called the House of Representatives, was dissolved.
 al-Za'im also imprisoned many political leaders, such as Munir al-Ajlani, whom he accused of conspiring to overthrow the republic.
Operation Priboi ("Coastal Surf") was the code name for the Soviet mass deportation from the Baltic states on 25–28 March 1949.
 The action is also known as the March deportation by Baltic historians.
 More than 90,000 Estonians, Latvians and Lithuanians, labeled as enemies of the people, were deported to forced settlements in inhospitable areas of the Soviet Union.
 Over 70% of the deportees were women, and children under the age of 16.

 After the proclamation, he served as the Under Secretary of the Ustaše Foreign Affairs Ministry.
 In 1942, he was Pavelić's envoy to the Italian Second Army.
 In this role he entered into negotiations with Chetnik representatives Jevđeviċ, Grđiċ and Kraljeviċ.
 Then he served as Under Secretary in the Ustaše Interior Ministry, the "body directly responsible for concentration camps and repressive political apparatus".
 Vrančić was "decorated by Hitler in honor of his planning skills at the work of mass deportation".
Otto Adolf Eichmann (] ; 19 March 1906 – 1 June 1962) was a German Nazi SS-"Obersturmbannführer" (lieutenant colonel) and one of the major organizers of the Holocaust.

"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."
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.
The deportation of Azerbaijanis from Armenia took place as an act of forced resettlement and ethnic cleansing throughout the 20th century.
 Prior to the October Revolution, Azerbaijanis had made up 43 percent of the population of Yerevan.
 The Tartar (i.e. Azerbaijani) population endured a process of forced migration from the territory of the Democratic Republic of Armenia and later in the Armenian SSR several times during the 20th century.
 Under Stalin's policies, approximately 100,000 Azerbaijanis were deported from the Armenian SSR in 1948.
 Their houses were subsequently inhabited by Armenian repatriates who arrived in the Soviet Union from abroad.
Rudolf "Rudi" Vrba (11 September 1924 – 27 March 2006) was a Slovak-Jewish biochemist who, as a teenger in 1942, was deported to the Auschwitz concentration camp in German-occupied Poland.
 He became known for having escaped from the camp in April 1944, at the height of the Holocaust, and for co-writing a detailed report about the mass murder that was taking place there.
 Distribution of the report is credited with having halted the mass deportation of Hungary's Jews to Auschwitz in July 1944, saving over 200,000 lives.
 After the war Vrba became a noted biochemist in England and Canada.
