How it ended, as its article says
Replaced by Second Czechoslovak Republic, 1939-03. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
It was replaced by the Second Czechoslovak Republic, which lasted less than half a year before Germany occupied the rest of Czechoslovakia in March 1939.

2 rulers, 2 with terms dated as terms, covering 1918 – 1938. Only 20 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”.
