Cyril and Methodius in the context of "Glagolitic alphabet"

Sts. Cyril and Methodius Church (Serbian: Храм светих Кирила и Методија/Hram svetih Kirila i Metodija, Slovene: Cerkev sv. Cirila in Metoda), commonly known as the Orthodox Church (Slovene: Pravoslavna cerkev, Serbian: Pravoslavna crkva), is an Eastern Orthodox church building located in Trubar Park (Slovene: Trubarjev park), between Bleiweis Street (Bleiweisova cesta) and Prešeren Street (Prešernova cesta), north of the Museum of Modern Art and west of the National Gallery of Slovenia. It belongs to the Metropolitanate of Zagreb and Ljubljana of the Serbian Orthodox Church and is named after Saints Cyril and Methodius, brothers known as the "Apostles to the Slavs."

Built in Serbo-Byzantine Revival, the church has five domes with golden crosses at their top. It was built from 1932 to 1936 by Ivan Bricelj based on plans by the architect Momir Korunović. The frescoes in the interior were painted by the Serbian painters Dragomir Jašović, Miša Mladenović, and Danica Mladenovič from 1986 until 1997. The iconostasis is work of a prominent woodcarver workshop from Debar (Macedonia) and has been decorated with icons by the Slovene painter Mirko Šubic [sl], who created them in 1940.

The history of the Czech lands – an area roughly corresponding to the present-day Czech Republic – starts approximately 800 years BCE. A simple chopper from that age was discovered at the Red Hill (Czech: Červený kopec) archeological site in Brno. Many different primitive cultures left their traces throughout the Stone Age, which lasted approximately until 2000 BCE. The most widely known culture present in the Czech lands during the pre-historical era is the Únětice Culture, leaving traces for about five centuries from the end of the Stone Age to the start of the Bronze Age. Celts – who came during the 5th century BCE – are the first people known by name. One of the Celtic tribes were the Boii (plural), who gave the Czech lands their first name Boiohaemum – Latin for the Land of Boii. Before the beginning of the Common Era the Celts were mostly pushed out by Germanic tribes. The most notable of those tribes were the Marcomanni and traces of their wars with the Roman Empire were left in south Moravia.

After the turbulent times of the Migration Period, the Czech lands were ultimately settled by the Slavic tribes. The year of 623 marks the formation of the first known state in the Czech lands, when Samo united the local Slavic tribes, defended their lands from the Avars to the east and – few years later – won the battle of Wogastisburg against the Franks invading the Czech lands from the west. The next state appearing in the Czech lands after the dissolution of the Samo's state was probably the Great Moravia. The center of its power lay in the area of Moravia and present-day western Slovakia. In 863, Cyril and Methodius, two scholars from Greece, brought Christianity to the Great Moravia and established the first Slavic script – Glagolitsa. The Great Moravia fell during the Magyar invasion at the start of the 10th century.

The history of Slovakia spans from prehistoric settlements to the modern Slovak Republic. Situated in Central Europe, the region’s earliest evidence of human habitation dates to the Palaeolithic era, with significant Neolithic and Bronze Age cultures. By the Iron Age, Celtic tribes like the Boii established settlements, later displaced by Germanic and Slavic migrations. The Slavs arrived in the 5th–6th centuries, forming the basis of Slavic states like Great Moravia (9th century), which adopted Christianity through Cyrillo-Methodian missionary activity.

Following Great Moravia’s collapse, the territory became part of the Kingdom of Hungary, enduring Mongol invasions and later Ottoman Wars that split Hungary into three parts. Much of present-day territory of Slovakia resisted Ottoman conquest and became a province of the Habsburg monarchy. The 19th century saw the rise of Slovak nationalism, fueled by figures like Ľudovít Štúr, who codified modern Slovak, and movements advocating autonomy within Austria-Hungary.

Saint Clement (or Kliment) of Ohrid (Bulgarian, Macedonian, Serbian: Климент Охридски, Kliment Ohridski; Ancient Greek: Κλήμης τῆς Ἀχρίδας, Klḗmēs tē̂s Akhrídas; Slovak: Kliment Ochridský; c. 830 – 916) was one of the first medieval Bulgarian saints, scholar, writer, and apostle to the Slavs. He was one of the most prominent disciples of Cyril and Methodius and is often associated with the creation of the Glagolitic and Cyrillic scripts, especially their popularisation among Christianised Slavs. He was the founder of the Ohrid Literary School and is regarded as a patron of education and language by some Slavic people. He is considered to be the first bishop of the Bulgarian Orthodox Church, one of the Seven Apostles of Bulgarian Orthodox Church since the 10th century, and one of the premier saints of modern Bulgaria. The mission of Clement was the crucial factor which transformed the Slavs in then Kutmichevitsa (present-day Macedonia) into Bulgarians. Clement is also the patron saint of North Macedonia, the city of Ohrid and the Macedonian Orthodox Church.
