Viceroy of Muscovy: What colony? Who was he?

Viceroy, one who rules a country or province as the representative of his sovereign or king and who is empowered to act in the sovereign’s name. Viceroy (virrey) was the title given to the principal governors of Spain’s American colonies, as well as to the governors of the “kingdoms” (reinos) of peninsular Spain proper (e.g., Aragon, Valencia).

• Viceroy - Britannica​

A viceroy is an official who runs a polity in the name of and as the representative of the monarch of the territory. The term derives from the Latin prefix vice-, meaning "in the place of" and the French word roy, meaning "king".

• The term has occasionally been applied to the governors-general of the Commonwealth realms, who are viceregal representatives of the monarch.
• Viceroy is a form of royal appointment rather than noble rank.

I remember running into this Viceroy of Muscovy flag a while ago.

Today I've run into the same flag in Google Images.

We can also see it as flag #154 in this 1832 pub.

This made me wonder in what colony Muscovy/Moscovy had its own Viceroy. Was thinking about Alaska, but... wouldn't it be the Viceroy of Russia instead of Muscovy?

• Grand Duchy of Moscow (1263–1547):​

Question #1: Why do we have a flag of the Viceroy of Muscovy in 1832-38?

• Muscovy (in any shape or form) ceased to exist in 1721.​

Question #2: What Russian colony other than Alaska (and may be California) do we know?

Question #3: What was the name of the Viceroy of Muscovy?

1894 source: In Furthest Ind. The Narrative of Mr. Edward Carlyon of the Honourable East India Company's Service.


KD: This is probably my ignorance but I have no clue what this is all about. I tried to google the info out but that did not produce any info.

• This "Viceroy of Muscovy" thing... could it be that Russia was itself a colony of some other country?
• Is there a difference between these two:
  • Viceroy of Muscovy
  • Viceroy from Muscovy
• Do we have any names of the people who might have served as Viceroys of/from Muscovy.
  • What colony could/would it be?
• When did they start and stop using this flag?

Update: Found the below excerpt in this 1878 pub.

• Description of the Land of the Samoyeds in Tartary, Recently Brought Under the Dominion of the Muscoviters
  • Translated from the Russian Language in the Year 1609 : with an Account of the Search After and Discovery of the New Passage Or Strait in the North West to the Empires of China & Cathay; and a Memorial Presented to the King of Spain Concerning the Discovery and Situation of the Land Called Australia Incognita

What do we not know about some unknown country of Samoyed People that would/could require a Viceroy of Muscovy being present there?

• Or was it this country after all?
