Peter II, 1715–30, czar of Russia (1727–30). A grandson of Peter I and the son of the czarevich Alexis, he succeeded on the death of Catherine I. He was too young to rule, but he willingly lent himself to a court intrigue, led by the Gallitzin and Dolgoruki families, which resulted in the fall of the all-powerful minister, A. D. Menshikov. Peter was betrothed to Catherine Dolgoruki, but died of smallpox on his wedding day. He was succeeded by his cousin Anna (Anna Ivanovna).
