How to say "conqueror" in Japanese

• 覇者はしゃCommon
  nounA common word for the conqueror in the sense of the one on top — the champion who dominates and reigns. Fits the winner of a tournament or the dominant power in a field.
• 征服者せいふくしゃ
  nounThe direct word for a conqueror: someone who conquers and subjugates a land, country, or people by force. The natural choice when the sense is literally conquering territory or peoples.
• 勝利者しょうりしゃ
  nounReally 'winner; victor' — the one who wins a contest, match, or battle. For 'conqueror' it is only a loose fit: choose it when you simply mean the side that prevailed.
  群集ぐんしゅうは勝利者しょうりしゃを歓呼かんこして迎むかえた。↗

  The crowd hailed the winner.
• 戦勝者せんしょうしゃ
  nounA less common word really denoting the victor, or the victorious troops, in a war. As 'conqueror' it is marginal — seldom the word you want; think 'victor in a war' instead.

Use 征服者 for a literal conqueror of lands or peoples, 覇者 for the conqueror as reigning champion on top, and treat 勝利者 and 戦勝者 as victor words that fit 'conqueror' only loosely.
