Where it sits in time
Five thousand years, 3000 BCE to 2026; the state in gold.
How it ended, as its article says
Partitioned by his surviving sons. Read from the article's section “History - Decline” by its grammar; the claim is only that the article says so.
After his defeat at the Battle on the river Nemiga and temporary imprisonment, Vseslav died, and the principality was divided between his surviving sons.

4 rulers, 3 with terms dated as terms, covering 988 – 1044. Median reign 13 years. 0 of 2 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”.

What led to it, and what came of it
The investigation's own picture: 1 cause the record names and 1 result, the strongest six of each at their own years, joined to the state by the kind of claim - a recorded statement solid, the article's sentence dashed, a theory dash-dot.
Open the investigation: every row with its evidence, the conditions at the time, the theories condition by condition, and the succession analysed.
