Politics and industry meet on August 29 in Bulgaria’s history: a prince’s quiet blessing for the 1885 union with Eastern Rumelia, and the 1954 launch of the chemical works that reshaped Devnya.
August 29, 1885 — Winning the Prince Over
In Shumen, where Prince Alexander of Battenberg was overseeing military exercises, two conspirators from the secret unionist movement — Captain Sava Mutkurov and Dimitar Rizov — met privately with the prince to sound him out on a planned union of Eastern Rumelia with the Principality of Bulgaria. Alexander gave his quiet backing, even as his own prime minister judged the plan premature.
Just over a week later, on September 6, the union was declared — one of the defining achievements of modern Bulgarian statehood.
August 29, 1954 — Devnya’s Chemical Giant Comes Online
The soda-ash plant “Karl Marx” began operations in Devnya, the first in what would grow into a sprawling industrial complex nicknamed the “Valley of Chimneys.” Cement, sugar, and power plants joined it over the following decades.
The area became one of communist Bulgaria’s most important industrial centres, prized for its economic output but increasingly notorious among residents for its environmental toll.
