On 29 July 1014, a Bulgarian army walked into a trap in a mountain pass in the far southwest, and by nightfall the fight for Bulgaria's independence had, for practical purposes, been decided a thousand years ago. That's a heavy way to start a Wednesday, so let's balance it: today's calendar also hands us a much gentler subject, a name rooted in a shrub full of red berries.
What happened on this day
For weeks, Emperor Basil II had been throwing his Byzantine army at a fortified pass in the Struma valley, the natural chokepoint between the Belasitsa and Ograzhden mountains near the village of Klyuch, and getting nowhere against Tsar Samuil's wooden palisades. What broke the deadlock wasn't a bigger push, it was a scout. The general Nikephoros Xiphias found a route up and over the mountains, brought his men down behind the Bulgarian lines, and on 29 July the position collapsed from the rear. Samuil's son, Gabriel Radomir, fought a desperate rearguard action near Mokrievo just to get his father out alive, and the tsar escaped north to Prilep.
What happened to the men who didn't escape is the part that earned Basil his enduring nickname, the Bulgar-Slayer. Byzantine sources say the captured soldiers were split into groups of a hundred, ninety-nine of each group blinded, one man in every hundred left with a single working eye so he could lead the rest of them home. The headline number depends on which chronicler you read: the historian Skylitzes says 15,000 men, the soldier-writer Kekaumenos says 14,000, and a later Bulgarian chronicle puts it lower still, at 8,000. Nobody was carefully counting at the time, and it hardly matters which figure is exact, the point the sources agree on is the scale of it. Samuil, watching the column of blinded veterans arrive, reportedly collapsed on the spot. He died two months later, on 6 October 1014, at Prespa, in what reads like a stroke or a heart attack brought on by the shock.
It's tempting to call Kleidion the battle that ended Bulgaria, and plenty of textbooks do, but that overstates it slightly: the state staggered on under Samuil's successors for another four years before Basil finally finished the conquest in 1018. Kleidion broke the army and, by most accounts, broke the tsar. It didn't, quite, break the country in a single afternoon.
Today's name days
Kalin and Kalina are the male and female forms of the same name, and neither one is tied to a Christian saint, they're straightforwardly secular, drawn from kalina, the Bulgarian word for the guelder rose, a shrub that produces clusters of bright red berries in autumn. It's a genuinely common image in Bulgarian folk song, kalina turns up again and again as a symbol of youth, beauty and sometimes grief, the sort of plant a grandmother would have a proverb about.
Kalinka is simply the affectionate diminutive of Kalina, the version you'd actually use for a child or a close friend. Goran is a different root entirely, from gora, the Slavic word for forest or wooded mountain, so the name lands somewhere close to "man of the woods". It's common right across the old Yugoslav space as well as Bulgaria. If any of these four are your name, or you want the fuller spread of variants that share these roots, the Bulgarian name-days guide has the complete list.
Here's the bit that still catches British expats out after years here: a Bulgarian name day doesn't work on the British invitation system. If it's a proper celebration, the person's home is effectively open house, colleagues, neighbours and friends turn up unannounced through the afternoon and evening. The one rule that actually matters is that you never arrive empty-handed, a cake, a banitsa, a box of chocolates or a bottle of wine all do the job, and if you're bringing flowers for a woman, make it an odd number, even numbers are for funerals.
Why this matters for British expats
Geographically, today's history lesson has nothing to do with Shumen, Kleidion's mountain pass is down in the far southwest, the better part of a day's drive from here near the modern Blagoevgrad-Greece border, closer to Thessaloniki than to us. If you want the local angle, it's cultural rather than geographic: the kalina bush behind two of today's names is the same plant you'll hear referenced in Bulgarian folk songs at weddings and festivals, so recognising the word gives you a small head start on a tradition that predates the Ottoman period by centuries.
The more immediately useful takeaway is the etiquette one. Get invited, formally or not, to a Kalin's or Goran's name day this year, and turning up with nothing in your hands is the one move that actually reads as rude here.

Frequently Asked Questions
What was the Battle of Kleidion?
It was a decisive battle on 29 July 1014 in which the Byzantine emperor Basil II trapped and defeated the army of the Bulgarian tsar Samuil in a mountain pass in the Struma valley, in Bulgaria's modern southwest.
Why do the sources disagree on how many soldiers were blinded?
Medieval chroniclers rarely had access to reliable headcounts. Skylitzes gives 15,000, Kekaumenos gives 14,000, and a later Bulgarian chronicle gives 8,000. All agree the number was large and the act was deliberate.
Is today a public holiday in Bulgaria?
No. 29 July 2026 falls on an ordinary Wednesday, with no public holiday or Shumen city event attached to it.
What should I bring if I'm invited to a name-day gathering for a Kalin, Goran, Kalina or Kalinka?
Never go empty-handed. Cake, banitsa, chocolates or wine are all safe choices, and flowers are welcome for the women, provided the bunch is an odd number.
Is there anywhere to visit connected to the Battle of Kleidion?
The pass lies near the village of Klyuch in Blagoevgrad Province, in Bulgaria's far southwest, well outside the Shumen area.
