How it ended, as its article says
Dissolved, 1795. Read from the article's section “History - Last years (1789–97)” by its grammar; the claim is only that the article says so.
The county of Flanders officially ceased to exist in 1795, when it was annexed by France, and divided into two departments: Lys (present day West Flanders) and Escaut (present day East Flanders and Zeelandic Flanders).

Rulers
The line of Count of Flanders - the office this state names as its head of state.

4 rulers, 3 with terms dated as terms, covering 1191 – 1244. Median reign 11 years. 1 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”.
