How it ended, as its article says
Replaced. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
It was transformed into the Lordship of Brecknock and later formed the southern and larger part of the historic county of Brecknockshire.

6 rulers, 4 with terms dated as terms, covering 450 – 950. Median reign 10 years. 0 of 3 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”.
