Tsarevich Peter became heir to the Russian throne in February 1718 after the Emperor removed his eldest son, Alexis Petrovich, from the succession.

His parents were Tsar Peter I and the future Catherine I.

Peter Petrovich was born on 15 November 1715 in Saint Petersburg as the son of Tsar Peter I and Tsaritsa and future Empress Catherine I.

In 1715, Tsarevich Alexis tried to flee but was brought back in 1718 and investigated, he was tortured and forced to renounce his rights to the Russian throne and recognize Peter Petrovich as the new Tsarevich and heir apparent.

Peter Petrovich died on 19 April 1719 in Saint Petersburg and was firstly buried in the Church of the Resurrection of Lazarus of the Alexander Nevsky Monastery, in 1723 he was reburied in the Annunciation Church leading to rumors that Tsar Peter had another son named Peter Petrovich born in 1719 but this was later proven false.
