Passage: As of 1878, there were only three free Slavic states in the world: the Russian Empire, Serbia and Montenegro. Bulgaria was also free but was de jure vassal to the Ottoman Empire until official independence was declared in 1908. In the entire Austro-Hungarian Empire of approximately 50 million people, about 23 million were Slavs. The Slavic peoples who were, for the most part, denied a voice in the affairs of the Austro-Hungarian Empire, were calling for national self-determination. During World War I, representatives of the Czechs, Slovaks, Poles, Serbs, Croats, and Slovenes set up organizations in the Allied countries to gain sympathy and recognition. In 1918, after World War I ended, the Slavs established such independent states as Czechoslovakia, the Second Polish Republic, and the State of Slovenes, Croats and Serbs.

Passage: During World War II, Hitler's Generalplan Ost (general plan for the East) entailed killing, deporting, or enslaving the Slavic and Jewish population of occupied Eastern Europe to create Lebensraum (living space) for German settlers. The Nazi Hunger Plan and Generalplan Ost would have led to the starvation of 80 million people in the Soviet Union. These partially fulfilled plans resulted in the deaths of an estimated 19.3 million civilians and prisoners of war.

Passage: The first half of the 20th century in Russia and the Soviet Union was marked by a succession of wars, famines and other disasters, each accompanied by large-scale population losses. Stephen J. Lee estimates that, by the end of World War II in 1945, the Russian population was about 90 million fewer than it could have been otherwise.

Passage: Because of the vastness and diversity of the territory occupied by Slavic people, there were several centers of Slavic consolidation. In the 19th century, Pan-Slavism developed as a movement among intellectuals, scholars, and poets, but it rarely influenced practical politics and did not find support in some nations that had Slavic origins. Pan-Slavism became compromised when the Russian Empire started to use it as an ideology justifying its territorial conquests in Central Europe as well as subjugation of other ethnic groups of Slavic origins such as Poles and Ukrainians, and the ideology became associated with Russian imperialism. The common Slavic experience of communism combined with the repeated usage of the ideology by Soviet propaganda after World War II within the Eastern bloc (Warsaw Pact) was a forced high-level political and economic hegemony of the USSR dominated by Russians. A notable political union of the 20th century that covered most South Slavs was Yugoslavia, but it ultimately broke apart in the 1990s along with the Soviet Union.

Passage: Pan-Slavism, a movement which came into prominence in the mid-19th century, emphasized the common heritage and unity of all the Slavic peoples. The main focus was in the Balkans where the South Slavs had been ruled for centuries by other empires: the Byzantine Empire, Austria-Hungary, the Ottoman Empire, and Venice. The Russian Empire used Pan-Slavism as a political tool; as did the Soviet Union, which gained political-military influence and control over most Slavic-majority nations between 1945 and 1948 and retained a hegemonic role until the period 1989–1991.

Passage: Slavic standard languages which are official in at least one country: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Macedonian, Montenegrin, Polish, Russian, Serbian, Slovak, Slovene, and Ukrainian. The alphabet depends on what religion is usual for the respective Slavic ethnic groups. The Orthodox use the Cyrillic alphabet and the Roman Catholics use Latin alphabet, the Bosniaks who are Muslims also use the Latin. Few Greek Roman and Roman Catholics use the Cyrillic alphabet however. The Serbian language and Montenegrin language uses both Cyrillic and Latin alphabets. There is also a Latin script to write in Belarusian, called the Lacinka alphabet.

Passage: Proto-Slavic, sometimes referred to as Common Slavic or Late Proto-Slavic, is defined as the last stage of the language preceding the geographical split of the historical Slavic languages. That language was uniform, and on the basis of borrowings from foreign languages and Slavic borrowings into other languages, cannot be said to have any recognizable dialects, suggesting a comparatively compact homeland. Slavic linguistic unity was to some extent visible as late as Old Church Slavonic manuscripts which, though based on local Slavic speech of Thessaloniki, could still serve the purpose of the first common Slavic literary language.

Passage: The pagan Slavic populations were Christianized between the 6th and 10th centuries. Orthodox Christianity is predominant in the East and South Slavs, while Roman Catholicism is predominant in West Slavs and the western South Slavs. The religious borders are largely comparable to the East–West Schism which began in the 11th century. The majority of contemporary Slavic populations who profess a religion are Orthodox, followed by Catholic, while a small minority are Protestant. There are minor Slavic Muslim groups. Religious delineations by nationality can be very sharp; usually in the Slavic ethnic groups the vast majority of religious people share the same religion. Some Slavs are atheist or agnostic: only 19% of Czechs professed belief in god/s in the 2005 Eurobarometer survey.

Passage: The modern Slavic peoples carry a variety of mitochondrial DNA haplogroups and Y-chromosome DNA haplogroups. Yet two paternal haplogroups predominate: R1a1a [M17] and I2a2a [L69.2=T/S163.2]. The frequency of Haplogroup R1a ranges from 63.39% in the Sorbs, through 56.4% in Poland, 54% in Ukraine, 52% in Russia, Belarus, to 15.2% in Republic of Macedonia, 14.7% in Bulgaria and 12.1% in Herzegovina. The correlation between R1a1a [M17] and the speakers of Indo-European languages, particularly those of Eastern Europe (Russian) and Central and Southern Asia, was noticed in the late 1990s. From this Spencer Wells and colleagues, following the Kurgan hypothesis, deduced that R1a1a arose on the Pontic-Caspian steppe.

Passage: Marcin Woźniak and colleagues (2010) searched for specifically Slavic sub-group of R1a1a [M17]. Working with haplotypes, they found a pattern among Western Slavs which turned out to correspond to a newly discovered marker, M458, which defines subclade R1a1a7. This marker correlates remarkably well with the distribution of Slavic-speakers today. The team led by Peter Underhill, which discovered M458, did not consider the possibility that this was a Slavic marker, since they used the "evolutionary effective" mutation rate, which gave a date far too old to be Slavic. Woźniak and colleagues pointed out that the pedigree mutation rate, giving a later date, is more consistent with the archaeological record.

Question: Who searched for specifically Slavic sub-group of R1a1a [M17]?

Question: When did Marcin Woźniak search specifically for Slavic sub-group of R1a1a [M17]?

Question: The team that discovered M458 was led by who?
Passage: Pomors are distinguished by the presence of Y Haplogroup N among them. Postulated to originate from southeast Asia, it is found at high rates in Uralic peoples. Its presence in Pomors (called "Northern Russians" in the report) attests to the non-Slavic tribes (mixing with Finnic tribes of northern Eurasia). Autosomally, Russians are generally similar to populations in central-eastern Europe but some northern Russians are intermediate to Finno-Ugric groups.

Question: What is distinguished by the presence of Y Haplogroup N?

Question: Pomors are distinguished by the presence of what?

Passage: On the other hand, I2a1b1 (P41.2) is typical of the South Slavic populations, being highest in Bosnia-Herzegovina (>50%). Haplogroup I2a2 is also commonly found in north-eastern Italians. There is also a high concentration of I2a2a in the Moldavian region of Romania, Moldova and western Ukraine. According to original studies, Hg I2a2 was believed to have arisen in the west Balkans sometime after the LGM, subsequently spreading from the Balkans through Central Russian Plain. Recently, Ken Nordtvedt has split I2a2 into two clades – N (northern) and S (southern), in relation where they arose compared to Danube river. He proposes that N is slightly older than S. He recalculated the age of I2a2 to be ~ 2550 years and proposed that the current distribution is explained by a Slavic expansion from the area north-east of the Carpathians.

Question: I2a1b1 is typical of what populations?

Question: I2a1b1 is found being highest where?

Question: Haplogroup I2a2 is commonly found in what group of people?

Question: Hg I2a2 was believed to have arisen where?

Question: Who has split I2a2 into two clades?
Passage: In 2008, biochemist Boris Arkadievich Malyarchuk (Russian: Борис Аркадьевич Малярчук) et al. of the Institute of Biological Problems of the North, Russian Academy of Sciences, Magadan, Russia, used a sample (n=279) of Czech individuals to determine the frequency of "Mongoloid" "mtDNA lineages". Malyarchuk found Czech mtDNA lineages were typical of "Slavic populations" with "1.8%" Mongoloid mtDNA lineage. Malyarchuk added that "Slavic populations" "almost always" contain Mongoloid mtDNA lineage. Malyarchuk said the Mongoloid component of Slavic people was partially added before the split of "Balto-Slavics" in 2,000–3,000 BC with additional Mongoloid mixture occurring among Slavics in the last 4,000 years. Malyarchuk said the "Russian population" was developed by the "assimilation of the indigenous pre-Slavic population of Eastern Europe by true Slavs" with additional "assimilation of Finno-Ugric populations" and "long-lasting" interactions with the populations of "Siberia" and "Central Asia". Malyarchuk said that other Slavs "Mongoloid component" was increased during the waves of migration from "steppe populations (Huns, Avars, Bulgars and Mongols)", especially the decay of the "Avar Khaganate".

Question: Malyarchuk said that other Slavs "Mongoloid component" was increased during the waves of migration from what populations?
Passage: DNA samples from 1228 Russians show that the Y chromosomes analyzed, all except 20 (1.6%) fall into seven major haplogroups all characteristic to West Eurasian populations. Taken together, they account for 95% of the total Russian Y chromosomal pool. Only (0.7%) fell into haplogroups that are specific to East and South Asian populations. Mitochondrial DNA (mtDNA) examined in Poles and Russians revealed the presence of all major European haplogroups, which were characterized by similar patterns of distribution in Poles and Russians. An analysis of the DNA did not reveal any specific combinations of unique mtDNA haplotypes and their subclusters. The DNA clearly shows that both Poles and Russians are not different from the neighbouring European populations.
