Beslan school siegeThe Beslan school siege (also referred to as the Beslan school hostage crisis or the Beslan massacre) was a terrorist attack that started on 1 September 2004, lasted three days, involved the imprisonment of more than 1,100 people as hostages (including 777 children) and ended with the deaths of 333 people, 186 of them children, as well as 31 of the attackers. It is considered to be the deadliest school shooting in history.
Russian Revolution of 1905The Russian Revolution of 1905, also known as the First Russian Revolution, began on 22 January 1905. A wave of mass political and social unrest then began to spread across the vast areas of the Russian Empire. The unrest was directed primarily against the Tsar, the nobility, and the ruling class. It included worker strikes, peasant unrest, and military mutinies. In response to the public pressure, Tsar Nicholas II was forced to go back on his earlier authoritarian stance and enact some reform (issued in the October Manifesto).
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
Köppen climate classificationThe Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification.
CossacksThe Cossacks are a predominantly East Slavic Orthodox Christian people originating in the Pontic–Caspian steppe of Ukraine and southern Russia. Historically, they were a semi-nomadic and semi-militarized people, who, while under the nominal suzerainty of various Eastern European states at the time, were allowed a great degree of self-governance in exchange for military service. Although numerous linguistic and religious groups came together to form the Cossacks, most of them coalesced and became East Slavic-speaking Orthodox Christians.
