Pan-Slavism in the context of "Russian nationalism"

South Slavs are Slavic people who speak South Slavic languages and inhabit a contiguous region of Southeast Europe comprising the eastern Alps and the Balkan Peninsula. Geographically separated from the West Slavs and East Slavs by Austria, Hungary, Romania, and the Black Sea, the South Slavs today include Bosniaks, Bulgarians, Croats, Macedonians, Montenegrins, Serbs and Slovenes.

In the 20th century, the country of Yugoslavia (from Serbo-Croatian, literally meaning "South Slavia" or "South Slavdom") united a majority of the South Slavic peoples and lands—with the exception of Bulgarians and Bulgaria—into a single state. The Pan-Slavic concept of Yugoslavia emerged in late 17th-century Croatia, at the time part of the Habsburg monarchy, and gained prominence through the 19th-century Illyrian movement. The Kingdom of Serbs, Croats and Slovenes, renamed the Kingdom of Yugoslavia in 1929, was proclaimed on 1 December 1918, following the unification of the State of Slovenes, Croats and Serbs with the kingdoms of Serbia and Montenegro. With the breakup of Yugoslavia in the early 1990s, several independent sovereign states were formed.

The State of Slovenes, Croats and Serbs (Serbo-Croatian: Država Slovenaca, Hrvata i Srba / Држава Словенаца, Хрвата и Срба; Slovene: Država Slovencev, Hrvatov in Srbov) was a political entity that was constituted in October 1918, at the end of World War I, by Slovenes, Croats and Serbs (Prečani) residing in what were the southernmost parts of the Austro-Hungarian Empire. Although internationally unrecognised, this was the first incarnation of a Yugoslav state founded on the Pan-Slavic ideology. Thirty-three days after it was proclaimed, the state joined the Kingdom of Serbia to form the Kingdom of Serbs, Croats and Slovenes.

The Slavs were Christianized in waves from the 7th to 12th century, though the process of replacing old Slavic religious practices began as early as the 6th century. Generally speaking, the monarchs of the South Slavs adopted Christianity in the 9th century, the East Slavs in the 10th, and the West Slavs between the 9th and 12th century. Saints Cyril and Methodius (fl. 860–885) are attributed as "Apostles to the Slavs", having introduced the Byzantine-Slavic rite (Old Slavonic liturgy) and Glagolitic alphabet, the oldest known Slavic alphabet and basis for the Early Cyrillic alphabet.

The simultaneous missionary efforts to convert the Slavs by what would later become known as the Catholic Church of Rome and the Eastern Orthodox Church of Constantinople led to a 'second point of contention between Rome and Constantinople', especially in Bulgaria (9th–10th century). This was one of many events that preceded the East–West Schism of 1054 and led to the eventual split between the Greek East and Latin West. The Slavs thus became divided between Eastern Orthodoxy and Roman Catholicism. Closely connected to the competing missionary efforts of the Roman Church and the Byzantine Church was the spread of the Latin and Cyrillic scripts in Eastern Europe. The majority of Orthodox Slavs adopted Cyrillic, while most Catholic Slavs adopted the Latin, but there were many exceptions to this general rule. In areas where both Churches were proselytising to pagan Europeans, such as the Grand Duchy of Lithuania, the Croatian Duchy and the Principality of Serbia, mixtures of languages, scripts and alphabets emerged, and the lines between Latin Catholic (Latinitas) and Cyrillic Orthodox literacy (Slavia Orthodoxa) were blurred.

Pan-nationalism (from Ancient Greek πᾶν (pân) 'all' and French nationalisme 'nationalism') in the social sciences includes forms of nationalism that aim to transcend (overcome, expand) traditional boundaries of basic or historical national identities in order to create a "higher" pan-national (all-inclusive) identity, based on various common denominators. In relation to classical state nationalism, pan-nationalism manifests itself through various political movements that advocate the formation of "higher" (pan-national) forms of political identity, based on a regional or continental grouping of national states, such as Pan-Africanism, Pan-Americanism, Pan-Arabism, Pan-Asianism, Pan-Slavism, and Pan-Turkism. In terms of ethnic nationalism, pan-nationalism can also manifest itself through specific ethnic movements that advocate setting up "higher" (pan-national) forms of common identity that are based on ethnic grouping (for example: Pan-Germanism or Pan-Slavism). Other forms of nationalism also have their pan-national variants.

Some forms of pan-nationalism, such as Pan-Germanism, manifest themselves on two levels: wider - relating to the unity of all Germanic peoples - and narrower - relating to the unity of all ethnic Germans, also including (on either of those two levels) German-speaking Austrians and German-speaking Swiss people, many of who may not self-identify as strictly "German", while still belonging to the wider family of contemporary Germanic peoples.

Turanism, also known as Turanianism, pan-Turanism or pan-Turanianism, is a pan-nationalist political movement built around pseudoscientific claims of biological and linguistic connections between various ethnic groups of Eurasia. It revolves around the abandoned proposal of a Ural-Altaic language family, which hypothesizes that the Turkic, Mongolic, Tungusic, and Uralic peoples share Inner and Central Asian origins and therefore close cultural, ethnic, and linguistic bonds. Supporters of Turanism propose political unity among these groups, chiefly to oppose the cultural and political influences of the Indo-Europeans of Europe, West Asia, and South Asia, as well as the Sino-Tibetans of East Asia. The movement emerged in the 19th century to counter pan-nationalist ideologies such as pan-Germanism, and built upon the ideas of pan-Slavism (e.g. the idea of a "Turanian brotherhood and collaboration" was borrowed from the pan-Slavic concept of "Slavic brotherhood and collaboration").

Count Nikolay Pavlovich Ignatyev (Russian: Никола́й Па́влович Игна́тьев; 29 January [O.S. 17 January] 1832 – 3 July [O.S. 20 June] 1908) was a Russian statesman and diplomat who is best known for his policy of aggressive expansionism as the Russian ambassador to China and the Ottoman Empire. He was also the minister of the interior from 1881 to 1882, where he promoted ultraconservative and Slavic-nationalist policies.

In dealing with China, he secured a large slice of Chinese territory by the multi-lateral Treaty of Peking in 1860. As the Russian ambassador to the Ottoman Empire from 1864 to 1877, he worked to stir up pan-Slavic feeling and nationalism against the Ottomans, and had some responsibility for the Bulgarian rebellion of April 1876. He encouraged his government to declare war on Turkey in 1877, and after the decisive Russian victory, he negotiated the Treaty of San Stefano in 1878. It heralded greatly strengthened Russian influence in the Balkans. However, Britain and Austria-Hungary intervened and forced the retraction of the treaty.
