Cyrillic alphabet in the context of "Simeon I of Bulgaria"

Krum's dynasty (Bulgarian: Крумова династия) was the royal and later imperial family founded by the Khan of Bulgaria Krum (r. 803–814), producing the monarchs of First Bulgarian Empire between 803 and 991. During this period Bulgaria adopted Christianity, reached its greatest territorial extent and triggered a golden age of culture and literature. Under the patronage of these monarchs Bulgaria became the birthplace of the Cyrillic alphabet; Old Bulgarian became the lingua franca of much of Eastern Europe and it came to be known as Old Church Slavonic. As a result of the victory in the Byzantine–Bulgarian war of 913–927 the Byzantine Empire recognized the imperial title of the Bulgarian rulers and the Bulgarian Orthodox Church as an independent Patriarchate.

The last representative of the dynasty, Tsar Roman (r. 977–991), was succeeded by Tsar Samuel (r. 997–1014) of the Cometopuli dynasty, upon the former's death in Byzantine captivity in 997, after spending six years in prison. Samuel had made the last member of Krum's dynasty a nominal head of state in 977, in order to avoid conflict.

The West Slavs are Slavic peoples who speak the West Slavic languages. They separated from the common Slavic group around the 7th century, and established independent polities in Central Europe by the 8th to 9th centuries. The West Slavic languages diversified into their historically attested forms over the 10th to 14th centuries.

Today, groups which speak West Slavic languages include the Poles, Czechs, Slovaks, Silesians, Kashubians, and Sorbs. From the ninth century onwards, most West Slavs converted to Roman Catholicism, thus coming under the cultural influence of the Latin Church, adopting the Latin alphabet, and tending to be more closely integrated into cultural and intellectual developments in western Europe than the East Slavs, who converted to Eastern Orthodox Christianity and adopted the Cyrillic alphabet.

Great Moravia (Latin: Regnum Marahensium; Greek: Μεγάλη Μοραβία, Meghálī Moravía; Czech: Velká Morava [ˈvɛlkaː ˈmorava]; Slovak: Veľká Morava [ˈvɛʎkaː ˈmɔrava]; Polish: Wielkie Morawy, German: Großmähren), or simply Moravia, was the first major state that was predominantly West Slavic to emerge in the area of Central Europe, possibly including territories which are today part of the Czech Republic, Slovakia, Hungary, Austria, Germany, Poland, Romania, Croatia, Serbia, Ukraine and Slovenia. The formations preceding it in these territories were Samo's tribal union (631–658) and the Pannonian Avar state (567–822).

Centered on the Morava River – which gave the realm its name – the core encompassed today’s Moravia in the eastern Czech Republic and adjacent western Slovakia. The kingdom saw the rise of the first-ever Slavic literary culture in the Old Church Slavonic language as well as the expansion of Christianity, first via missionaries from East Francia, and later after the arrival of Saints Cyril and Methodius in 863 and the creation of the Glagolitic alphabet, the first alphabet dedicated to a Slavic language. Glagolitic was subsequently replaced by the Cyrillic alphabet created in the First Bulgarian Empire.

The Romanian Cyrillic alphabet is the Cyrillic alphabet that was used to write the Romanian language and Church Slavonic from the 14th century until the 1830s, when it began to be gradually replaced by a Latin-based Romanian alphabet. Cyrillic remained in occasional use until the 1920s, mostly in Russian-ruled Bessarabia.

From the 1830s until the full adoption of the Latin alphabet, the Romanian transitional alphabet was in place, combining Cyrillic and Latin letters, and including some of the Latin letters with diacritics that remain in the modern Romanian alphabet. The Romanian Orthodox Church continued using the alphabet in its publications until 1881.

The following is a list of the 47 cities and towns in Estonia. Before the Republic of Estonia became an independent nation in 1918, many of these locations were known in the rest of the world by their German names, which were occasionally quite different from the ones used in the Estonian. During the 1944–1991 Soviet occupation of Estonia, placenames were transliterated into Russian (Cyrillic alphabet) in the Soviet central government's documents, which in turn led to the use of several incorrect back-transliterations from Russian (Cyrillic) alphabet into English (and other Latin alphabets) in some English-language maps and texts during the second half of the 20th century (for example, incorrect Pyarnu, Vilyandi, Pylva, instead of the correct Pärnu, Viljandi, Põlva).

Tallinn is the capital and the most populous city of Estonia. There are 46 other linn, i.e. cities and towns in Estonia (as of 2022). The Estonian word linn means both 'city' and 'town'. More than 70% of the country's population lives in the cities and towns.

Capitalization (American English) or capitalisation (Commonwealth English) is writing a word with its first letter as a capital letter (uppercase letter) and the remaining letters in lower case, in writing systems with a case distinction. The term also may refer to the use of uppercase letters in general, or the choice between uppercase and lowercase.

Conventional writing systems (orthographies) for different languages have different conventions for capitalization, for example, the capitalization of titles. Conventions also vary, to a lesser extent, between different style guides. In addition to the Latin script, capitalization also affects the Armenian, Cyrillic, Georgian and Greek alphabets.
