Dolgorukov's birth date is unknown. From 1700 to 1706 he lived in
Warsaw and travelled to
Italy. The nobility of his father, Grigory Fyodorovich, and uncle Yakov Fyodorovich, made it quite easy for Alexey to work on different services. In 1713, he became governor of
Smolensk, in 1723, he became president of the Main Municipality and in 1726, after an appeal by
Alexander Danilovich Menshikov, was named senator and
hofmeister by
Catherine I. Dolgorukov was the second educator of
Grand Duke Peter Alexeyevich Romanov. In 1729, together with his family member
Vasily Vladimirovich Dolgorukov they arrested and exiled their rival
Alexander Danilovich Menshikov. Under Peter II, Dolgorukov became a member of the Supreme Privy Council. He tried to recover Peter II's rule while being against Menshikov. Finally, latter was exiled in
Beryozov of the
Tobolsk Governorate. As he endeavoured to go by Peter II, he distracted him from work, encouraging him in chases and other enjoyments. He often sent him to his manor in the region behind Moscow in Gorenky, where only family members of the Dolgorukovs were near him. Here the 14-year-old Emperor met with one of Alexey's daughters, Ekaterina, who became engaged with Peter II. After the death of Peter II, he was the only member of the Supreme Privy Council who protested against the accession of
Anna, leading him and his family being exiled to Beryozov, where he died in 1734. ==Personal life==
