the.com/iron fist

Authority that skips persuasion and goes straight to compliance.

means Harsh, unyielding control that relies on force or strict punishment rather than consent or kindness.

from A straightforward metaphor rather than a coined phrase with a single birth moment: a fist, already the universal image of force, gets dressed in iron to make the force unbreakable and unfeeling. English writers were using 'iron hand' and 'iron fist' for tyrannical rule by at least the 1800s, and the phrase gained extra political weight from the German 'Eiserne Faust' and similar phrases used in European rhetoric of the era. The companion phrase 'iron fist in a velvet glove' — power hidden under softness — shows how naturally the image invites being dressed up or down.
