Great Plague of Marseille: The Great Plague of Marseille was the last of the significant European outbreaks of bubonic plague.  Arriving in Marseille, France in 1720, the disease killed 100,000 people in the city and the surrounding provinces.  However, Marseille recovered quickly from the plague outbreak.  Economic activity took only a few years to recover, as trade expanded to the West Indies and Latin America.  By 1765, the growing population was back at its pre-1720 level.

The Darkroom of Damocles: The Darkroom of Damocles (Dutch: De donkere kamer van Damokles ) is a war novel by the Dutch writer Willem Frederik Hermans, published in 1958.  Osewoudt, an Amsterdam cigar store owner living under the Nazi occupation, makes his acquaintance with the mysterious Dorbeck, who claims to be involved in the Resistance movement.

Glinciszki massacre: The Glinciszki massacre was a mass murder of Polish civilians by the Nazi-subordinated Lithuanian Auxiliary Police Battalion, committed on 20 June 1944 in the village of Glinciszki (now Glitiškės, Vilnius District Municipality, Lithuania) during the occupation of Poland in World War II.  In the massacre, 39 hostages died, including 11 women (one in advanced stage of pregnancy), 11 children (some as young as 3 years old), and 6 elderly men.  They were executed as a collective punishment for the death of four Lithuanian Nazi policemen on the previous evening, during the skirmish with the Polish resistance units of the 5th Brigade of Armia Krajowa commanded by Lieutenant Wiktor Wiącki.  The massacre triggered an act of reprisal by the Polish partisans against Lithuanian civilians in Dubingiai two days later.

The Holocaust: The Holocaust, also referred to as the Shoah, was a genocide in which Adolf Hitler's Nazi Germany and its World War II collaborators killed some six million European Jews.

A broader definition of the Holocaust includes non-Jewish victims such as the Roma, ethnic Poles, other Slavic ethnic groups, and the disabled and mentally ill.  An even broader definition includes Soviet citizens and prisoners of war, homosexuals, Jehovah's Witnesses, black people, and political opponents of the Nazis.

Dubingiai massacre: The Dubingiai massacre was a mass murder of 20–27 Lithuanian civilians in the town of Dubingiai (Dubinki) on 23 June 1944.  The massacre was carried out by the 5th Brigade of Armia Krajowa (AK), a Polish resistance group, in a reprisal for the Glinciszki (Glitiškės) massacre of 20 June.  The Dubingiai massacre started a wider AK operation in which units beyond the 5th Brigade were involved.  In total, 70–100 Lithuanians were killed by the end of June 1944 in Dubingiai and the neighbouring villages of Joniškis, Inturkė, Bijutiškis, and Giedraičiai.  While Nazi collaborators were ostensibly the prime targets, the victims included the elderly, children, and even infants.  Further conflicts between Lithuanian and Polish units were prevented by the Soviet capture of Vilnius in mid-July.
