How it ended, as its article says
Conquered by invaded again in 1894, 1894. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
France invaded again in 1894 and conquered the kingdom, making it a French colony, in what became known as the Franco-Hova Wars.
