noun
the Red Peril; communist threat
Historical and ideological term used primarily in early-to-mid 20th century discourse to refer to the perceived danger of communism or leftist movements. Now largely archaic outside historical or rhetorical contexts.
戦前の日本では、赤禍という言葉が反共プロパガンダで使われた。
In prewar Japan, the term 'Red Peril' was used in anti-communist propaganda.
Compound of 赤 (red, symbolizing communism) and 禍 (calamity, disaster). The exact historical origin is uncertain, but it likely emerged in early 20th-century Japanese political discourse as a translation or adaptation of Western anti-communist rhetoric.
