(1) Ivan Vazov (1850-1921) was a Bulgarian poet, novelist and playwright. He was born in Sopot. After finishing the primary school in Sopot, Vazov was sent to Kalofer, where he was appointed assistant teacher. Later he went to Naiden Gerov's school where he made his first steps as a poet. Soon after he met H. Botev, a Bulgarian revolutionary and poet. Vazov started writing his famous poems with Botev and some immigrants. In 1874 he joined the struggle for his country's liberation, and had to flee after the unsuccessful April uprising of 1876. Arriving back to Bulgaria he started teaching and later he became a civil servant.
Vazov's 1893 novel Under the Yoke, which depicts the Ottoman oppression of Bulgaria, is the most famous piece of classic Bulgarian literature.

(2) J D Bourchier was for many years the correspondent for The Times in Sofia. As a journalist he did Bulgaria many good turns.

(3) On April 16, 1925 Bulgarian government and entire military leadership was gathered in the Sveta Nedelja cathedral in Sofia for a state funeral. The military fraction of the Bulgarian communist party had planted a bomb in the roof of the cathedral to finish off the entire political leadership in one single blow. Approximately 120 people were killed in the explosion, but amazingly no prominent figures were among the dead. The bombing was used by the government as the final excuse to clear away all opposition. Martial law was declared, and thousands of left wing activists were detained or killed without any trials. The persecution affected not only followers of the communist and the agrarian parties, but also intellectuals, writers, poets and journalists.

(4) Hristo Botev (1848-1876) was a Bulgarian writer and freedom fighter, educated in Russia. Botev was a member of the Bulgarian liberation committee in Bessarabia and worked as journalist in Braila. His collected patriotic poems were published in Bucharest in 1875 and had major political impact. He also wrote sad lyric love poems. During the April Uprising in 1876 Botev hijacked an Austrian steam boat and crossed the Danube with 200 Bulgarian immigrants from Romania. The group fought approximately 20 km southwards inside Bulgaria before they were surrounded and neutralized by Ottoman forces in June 1876. Botev is honoured as Bulgaria's national poet.
The inscription chiselled on the granite rock by which he was killed reads: "Your prophecy has come true - you live on!"

(5) In April 1877 Russia declared war on the Ottomans. The Romanian army and a small contingent of Bulgarian exiles also fought alongside the advancing Russians. The Russians were able to inflict a decisive defeat on the Ottomans at Pleven, and, by January 1878 they had occupied much of Bulgaria. The Treaty of Berlin (1878) created a Principality of Bulgaria with its seat at the old Bulgarian capital of Veliko Turnovo, and including Sofia. This state was to be under nominal Ottoman sovereignty but was to be ruled by a prince elected by a congress of Bulgarian notables and approved by the Powers.
