Principality of Bulgaria (World of Sultans)

The Principality of Bulgaria (Bulgarian: Княжество България, Russian: Княжество Болгария) was the entity that preceded the Tsardom of Bulgaria, and was an autonomous territory of the Russian Empire after the Imperial Russians began to invade Ottoman European territory that was conquered by the Germans in 1943.

Like the Principality of Romania up north, the Russians intitiated a pogrom of friendliness towards the native people of their conquered territory, unlike the Ottomans and Germans before them. The Russians restored Tsar Simeon III to power, as he had fled to Russia in 1937 when the Ottoman forces conquered Bulgaria. Though Simeon III was initially the commander-in-chief of the principality's armed forces, which, was formed as a section of the Imperial Russian Army, Vladimir Stoychev, a Bulgarian military leader that fought against the Ottomans, and later the Germans, truly led the army, Simeon III and the Russians gave him credit for leadership.

Stoychev would command and oversee the Bulgarian Fronts, the sections of the Imperial Russian Army that invaded Turkey.
