[1] In 1609 Filaret fell into the hands of False Dmitriy II, who named him Patriarch of all Russia, though his jurisdiction only extended over the very limited area which acknowledged the impostor.

He was released on the conclusion of the Truce of Deulino (13 February 1619), and on 24 June of the same year was canonically enthroned Patriarch of Moscow[1] and all of Russia.

[1] Filaret's zeal for the purity of Orthodoxy sometimes led him into excesses but he encouraged the publication of theological works, formed the nucleus of the subsequently famous Patriarchal Library, and commanded that every archbishop should establish a seminary for the clergy, himself setting the example.

His death in October 1633 put an end to the Russo-Polish War (1632–33), withdrawing the strongest prop from a tsar feeble enough even when supported by all the weight of his authority.

Each department was headed by a patriarchal boyar (a member of the highest rank of the Russian aristocracy) and staffed with clerks and scribes.

The patriarch was instrumental in the establishment of the Romanov dynasty through his use of ostentatious ceremonies and architectural projects which succeeded in underlining the importance of the Crown.
