The Slovakia 2013 Constantine and Methodius 2 euro commemorative coin honours the two Byzantine Greek brothers who played a pivotal role in the cultural and religious history of the Slavic peoples. The national side features the figures of Constantine and Methodius standing beside a double-barred cross, which is a significant national symbol of Slovakia, mounted on three hills. This design commemorates the 1150th anniversary of the arrival of the brothers in Great Moravia, an event that marked the introduction of the Old Church Slavonic language and the Glagolitic alphabet to the region. Their mission laid the foundation for Slavic literacy and Christian tradition, profoundly shaping the nation's identity and historical development. This coin was issued in 2013 with a mintage of 978,700 pieces.
