Peter II Alexeyevich was Emperor of Russia from 1727 until 1730, when he died at the age of 14. He was the only son of Tsarevich Alexei Petrovich and Charlotte Christine of Brunswick-Lüneburg. After Catherine I's death, Alexander Menshikov controlled Peter II, but was thwarted by his opponents and exiled by Peter. Peter was also influenced by favorites like Prince Aleksey Dolgorukov, leading to a neglect of state affairs and the tightening of serfdom. Peter's reign was marked by disengagement, disorder, and indulgence. He was engaged to Ekaterina Dolgorukova, but died suddenly of smallpox before the marriage, thus making him the last male agnatic member of the House of Romanov.

The emperor and autocrat of all Russia, also translated as emperor and autocrat of all the Russias, was the official title of the Russian monarch from 1721 to 1917.
