How it ended, as its article says

Conquered by Moscow. Read from the article's section “lead” by its grammar; the claim is only that the article says so.

Dmitry Donskoy secured control over Beloozero and passed it to his descendants; it was formally annexed to Moscow by Ivan III.

2 rulers, 2 with terms dated as terms, covering 1238 – 1279. Only 41 years of the line are dated - too short for a median. 0 of 1 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. A blank in the last column means no kin on record, which is coverage, never “unrelated”.
