Claim
He became a boyar in 1550
Correction

This date is too late. Scholarly and reference sources place Fyodorov-Chelyadnin in the rank of boyar by 1546 or, at the latest, 1547—not 1550.

Full reasoning

The claim gives 1550 as the year Ivan Petrovich Fyodorov-Chelyadnin became a boyar, but the available historical references place his promotion earlier.

  • A 2019 scholarly article on the composition of the Boyar Duma states that Fyodorov was already "boyar and konyushy" on 21 July 1546, and then lists him as boyar from 21 July 1546 until 11 September 1568.
  • The Great Russian Encyclopedia likewise describes him as "boyar and konyushy (until July 1546, from July 1547)", meaning he already held that status before his 1546 disgrace and again after his restoration in 1547.

So the article's statement that he became a boyar in 1550 is inconsistent with the cited historical literature, which places him in that rank several years earlier.
