Classical music has often incorporated elements or material from popular music of the composer's time. Examples include occasional music such as Brahms' use of student drinking songs in his Academic Festival Overture, genres exemplified by Kurt Weill's The Threepenny Opera, and the influence of jazz on early- and mid-20th-century composers including Maurice Ravel, exemplified by the movement entitled "Blues" in his sonata for violin and piano.

Title: Slavs

Slavs are the largest Indo-European ethno-linguistic group in Europe. They inhabit Central Europe, Eastern Europe, Southeast Europe, North Asia and Central Asia. Slavs speak Indo-European Slavic languages and share, to varying degrees, some cultural traits and historical backgrounds. From the early 6th century they spread to inhabit most of Central and Eastern Europe and Southeast Europe, whilst Slavic mercenaries fighting for the Byzantines and Arabs settled Asia Minor and even as far as Syria. The East Slavs colonised Siberia and Central Asia.[better source needed] Presently over half of Europe's territory is inhabited by Slavic-speaking communities, but every Slavic ethnicity has emigrated to other continents.

Present-day Slavic people are classified into West Slavic (chiefly Poles, Czechs and Slovaks), East Slavic (chiefly Russians, Belarusians, and Ukrainians), and South Slavic (chiefly Serbs, Bulgarians, Croats, Bosniaks, Macedonians, Slovenes, and Montenegrins), though sometimes the West Slavs and East Slavs are combined into a single group known as North Slavs. For a more comprehensive list, see the ethnocultural subdivisions. Modern Slavic nations and ethnic groups are considerably diverse both genetically and culturally, and relations between them – even within the individual ethnic groups themselves – are varied, ranging from a sense of connection to mutual feelings of hostility.

Title: Slavs

The Slavic autonym is reconstructed in Proto-Slavic as *Slověninъ, plural *Slověne. The oldest documents written in Old Church Slavonic and dating from the 9th century attest Словѣне Slověne to describe the Slavs. Other early Slavic attestations include Old East Slavic Словѣнѣ Slověně for "an East Slavic group near Novgorod." However, the earliest written references to the Slavs under this name are in other languages. In the 6th century AD Procopius, writing in Byzantine Greek, refers to the Σκλάβοι Sklaboi, Σκλαβηνοί Sklabēnoi, Σκλαυηνοί Sklauenoi, Σθλαβηνοί Sthlabenoi, or Σκλαβῖνοι Sklabinoi, while his contemporary Jordanes refers to the Sclaveni in Latin.

The English word Slav could be derived from the Middle English word sclave, which was borrowed from Medieval Latin sclavus or slavus, itself a borrowing and Byzantine Greek σκλάβος sklábos "slave," which was in turn apparently derived from a misunderstanding of the Slavic autonym (denoting a speaker of their own languages). The Byzantine term Sklavinoi was loaned into Arabic as Saqaliba صقالبة (sing. Saqlabi صقلبي) by medieval Arab historiographers. However, the origin of this word is disputed.

Alternative proposals for the etymology of *Slověninъ propounded by some scholars have much less support. Lozinski argues that the word *slava once had the meaning of worshipper, in this context meaning "practicer of a common Slavic religion," and from that evolved into an ethnonym. S.B. Bernstein speculates that it derives from a reconstructed Proto-Indo-European *(s)lawos, cognate to Ancient Greek λαός laós "population, people," which itself has no commonly accepted etymology. Meanwhile, others have pointed out that the suffix -enin indicates a man from a certain place, which in this case should be a place called Slova or Slava, possibly a river name. The Old East Slavic Slavuta for the Dnieper River was argued by Henrich Bartek (1907–1986) to be derived from slova and also the origin of Slovene.

According to eastern homeland theory, prior to becoming known to the Roman world, Slavic-speaking tribes were part of the many multi-ethnic confederacies of Eurasia – such as the Sarmatian, Hun and Gothic empires. The Slavs emerged from obscurity when the westward movement of Germans in the 5th and 6th centuries CE (thought to be in conjunction with the movement of peoples from Siberia and Eastern Europe: Huns, and later Avars and Bulgars) started the great migration of the Slavs, who settled the lands abandoned by Germanic tribes fleeing the Huns and their allies: westward into the country between the Oder and the Elbe-Saale line; southward into Bohemia, Moravia, much of present-day Austria, the Pannonian plain and the Balkans; and northward along the upper Dnieper river. Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa.

In the 7th century, the Frankish merchant Samo, who supported the Slavs fighting their Avar rulers, became the ruler of the first known Slav state in Central Europe, which, however, most probably did not outlive its founder and ruler. This provided the foundation for subsequent Slavic states to arise on the former territory of this realm with Carantania being the oldest of them. Very old also are the Principality of Nitra and the Moravian principality (see under Great Moravia). In this period, there existed central Slavic groups and states such as the Balaton Principality, but the subsequent expansion of the Magyars, as well as the Germanisation of Austria, separated the northern and southern Slavs. The First Bulgarian Empire was founded in 681, the Slavic language Old Bulgarian became the main and official of the empire in 864. Bulgaria was instrumental in the spread of Slavic literacy and Christianity to the rest of the Slavic world.

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.

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.
