July 5 Holiday: The Czech Republic and Slovakia celebrate the Feast of Saints Cyril and Methodius
On July 5, the Czech Republic and Slovakia celebrate the Day of Saints Cyril and Methodius—one of the most important religious and cultural holidays. It is dedicated to the brothers and educators who, in the 9th century, brought Christianity to the Slavic peoples, created the first Slavic alphabet, and laid the foundation for Slavic writing.
History of the Holiday
Saints Cyril and Methodius were Byzantine missionaries who were invited to the Great Moravian Empire in 863 to spread Christianity among the Slavs.
To translate liturgical texts, they created the first Slavic script—Glagolitic—which became the foundation for the development of the Slavic literary tradition. Their missionary work had an enormous impact on the spiritual, cultural, and educational development of many Slavic peoples.
Why Cyril and Methodius Are of Special Significance
The brothers are called the Apostles of the Slavs because they were the first to conduct religious services in a language the Slavs could understand. Their work contributed to the development of education, culture, and the spread of literacy in Central and Eastern Europe.
It was thanks to their work that the Slavic peoples gained the ability to read religious texts in their native language, which marked an important stage in the development of national culture.
How Cyril and Methodius Day Is Celebrated
In the Czech Republic and Slovakia, July 5 is an official national holiday. On this day, churches hold solemn services, and there are pilgrimages, historical reenactments, concerts of sacred music, and cultural events.
One of the main centers of the celebrations is the Czech city of Velehrad, which attracts thousands of pilgrims and tourists every year.
