It's 3rd of March - Bulgaria's brightest national holiday. It marks the liberation of Bulgaria from Ottoman repression.
In 1393, the Ottomans captured Veliko Tarnovo, the capital of the Second Bulgarian Empire and my home town, after a three-month siege. In 1396, the Vidin Tsardom fell after the defeat of a Christian crusade at the Battle of Nicopolis. With this the Ottomans finally subjugated and occupied Bulgaria.
