Imagine living in a world where your language exists… but there’s no alphabet to write it down. That’s what it was like in Great Moravia in the 9th century – until two clever brothers, Cyril a Metoděj, changed everything.
These two weren’t just your average monks. Nope, they were superstars of their time. Sent from Byzantium (today’s Greece) in 863, their mission was to help the Slavic people understand Christianity in their own language. But there was a problem: no one had ever written down Old Slavic before.
So what did they do? Invent an alphabet, of course.
✍️ Say hello to Hlaholice

Cyril came up with a brand-new script called Hlaholice (Glagolitic). It looked very artsy – kind of like mysterious runes – and was the first step in giving Slavic people their own written word. Later, Cyril’s students simplified it into what we know today as the Cyrillic alphabet (yep, it’s named after him!).
Thanks to Cyril and Metoděj, the Slavs could finally read the Bible in their own language, which was a game-changer for spreading literacy and culture.
👣 Why do Czechs care so much?
In the Czech Republic, Cyril and Metoděj are big deals. They’re even celebrated with a national holiday on 5. července (July 5) every year. On this day, you’ll hear about their work as “Slovanští věrozvěstové” (Slavic missionaries) and see people attending church services or cultural events.
Their mission wasn’t easy. They faced political enemies and even went to Rome to defend their work. But their dedication left a mark that’s still felt over 1,100 years later.
🇨🇿 Quick Czech phrases to celebrate them:
Here are a few Czech words you’ll hear around this holiday:
- Svátek Cyrila a Metoděje – Feast of Cyril and Methodius
- věrozvěstové – missionaries (literally “faith-bringers”)
- písmo – script/font
- slovanský jazyk – Slavic language
🎉 Why you should care too
Cyril and Metoděj didn’t just bring religion – they brought language and literacy. For anyone learning Czech (hint hint), you could say they’re the OG language teachers. Without them, we might not even have the beautiful words you’re learning today.
So next time you write Dobrý den, give a little mental high five to the brothers who made it possible.
