Muraviev was educated at Robert College of Istanbul,[citation needed] just like Todor Ivanchov, Konstantin Stoilov and many other Bulgarians were at the time.

[2] However, on 2 September 1944 Muraviev was chosen by the Regency as Prime Minister in order to appeal to the Western Allies after they had rejected the advances of his predecessor Ivan Bagryanov.

[4] Muraviev had made overtures to the Fatherland Front although he was rebuffed as by this point they felt ready to establish their own government, rather than act as junior partners.

The scheme failed however as the Soviet Union promptly declared war on Bulgaria and, by the time Muraviev did likewise against Germany on 8 September it was too late.

Upon his release, Muraviev largely resigned himself to the new situation and in 1961 even held a series of discussions with Georgi Traykov, something for which he was condemned by his former colleagues on the right of the Agrarian Union.
