On 6 September each year, Bulgaria celebrates its Unification Day. 132 years ago on that day, two Bulgarian-majority entities joined together to form a united Bulgarian state.
The vassal Principality of Bulgaria, which before the Unification included more or less modern northern Bulgaria and the Sofia region, merged with the Ottoman autonomous province of Eastern Rumelia, roughly corresponding to Northern Thrace, or most of modern Southern Bulgaria.
The Unification of Bulgaria was a daring political act that defied the separation of the Bulgarian lands as per the Treaty of Berlin of 1878, which had formally restored Bulgarian statehood. And while the revolution itself was peaceful and cause for celebration among the majority of the population, it had to be successfully defended against the Serbs in the Serbo-Bulgarian War of the same year.
Traditionally, the biggest Unification celebrations take place in Plovdiv. As the former capital of Eastern Rumelia, Plovdiv was the site of the most important events associated with the act. Tonight, the city will host a formal ceremony attended by the president and a fireworks show.
Happy Unification Day to everyone!
