Duke Yuri Mikhailovich Bulgakov-Golitsyn (Russian: Юрий Михайлович Булгаков-Голицын) was a governor of Pskov province and Russian ambassador to Hungary in the 16th century.
Bulgakov came from a princely family which had roots in Ingria, eastern Finland, and Pskov region.
He was governor (or viceroy) of two important provinces: Pskov and Novgorod.
Ivan IV wanted to underline that he held a more exalted position as sovereign than the parvenu king Gustav of Sweden.
So, he forced Gustav to have contact with his governor of the border province of Pskov, and not directly with the central government in Moscow.
