Day of unification of Bulgaria (06/09)

The Day of the Unification of Bulgaria (Bulgarian. "Den for the Union") is a public holiday celebrated in the country annually on September 6, established in honor of the accession of Eastern Rumelia to the Principality of Bulgaria in 1885.

Under the Berlin Treaty of 1878, Bulgaria was essentially divided into three parts: the Principality of Bulgaria (with Sofia as its capital), the autonomous region of Eastern Rumelia (with Plovdiv as its center), and the Macedonia region, which remained part of the Ottoman Empire. The national doctrine of the young Bulgarian state bore fruit in 1885: under the pressure of the masses, an uprising began in Eastern Rumelia.

On September 6, 1885, rebel detachments led by Chardafon (Chardafon) entered Plovdiv and forced the ruler of the region to surrender his powers to the Provisional Government. Two days later, the Bulgarian prince Alexander Battenberg approved the accession of Eastern Rumelia to the Principality of Bulgaria with a special manifesto.
