authoritarianism
Refers to a political system or social attitude that demands strict obedience to authority, often at the expense of personal freedom. Used both as a noun and as a no-adjective.

権威主義に反対する声が高まって

全体主義 (totalitarianism) is a more extreme form where the state controls all aspects of life, while 権威主義 focuses on obedience to authority without necessarily controlling everything.
独裁主義 (dictatorship) emphasizes rule by a single person or small group, whereas 権威主義 can also describe a broader social or institutional attitude.
Compound of 権威 (authority) and 主義 (principle, -ism). The term is a modern coinage, likely influenced by Western political vocabulary.
