Ivan II "the
Meek" was the son of Grand Prince
Ivan I of
Russia. He was born in
1326 and came to the throne in
1353 on the death of his older
brother Simeon. As the
nickname implied, Ivan wasn't much of a fighter, but he did manage to hold Russia together and stave off
Lithuanian attacks from the west.
Many of his decisions were made on the advice of Orthodox Church leader Metropolitan Alexis, who Simeon had recommended as an advisor in his last testament. Ivan actually started out his reign denying support to the western cities attacked by the Lithuanians, but public opinion and Alexis' advice led him to change his mind.
Ivan died in 1359 and left his nine-year-old son Dmitry III Donskoi to be Grand Prince, with Alexis as advisor.
