How it ended, as its article says
Conquered by King of Prussia. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
Following Prussia's victory, Frankfurt was annexed by decree of the King of Prussia on 20 September, and became part of the newly formed Province of Hesse-Nassau.
