Regier'n is a colloquial, shortened form of "regieren," which means "to govern" or "to rule." It's a strong verb that implies control and power.
In the context of the song "Frauen regier'n die Welt" (Women Rule the World), it's used to humorously and playfully assert that women, through their charm and influence, are the true rulers of the world, even over traditional figures of power. This makes it a central and very enticing word for the song's theme.
Frauen regier'n die Welt is a cheeky big-band swing number by German crooner Roger Cicero that turns traditional power dynamics on their head. With tongue firmly in cheek, the singer confesses how women have quietly held the reins of his life since childhood: he joins ballet to impress a classmate, sews an eco-friendly slogan on his jacket just because she likes environmentalism, and generally bends over backward whenever a captivating smile is sent his way. The music’s lively brass and jazzy rhythm underline the playful message ‑- that a single flirtatious glance can open wallets, hearts, and even change political views faster than any boss, action hero, or mob money ever could.
The lyrics parade example after example of feminine influence, from babies who already have Dad wrapped around their tiny fingers to pop-culture icons and presidents whose fates are nudged by the women around them. Cicero is not lamenting this sway, he is celebrating it with a grin, suggesting that genuine power often hides behind charm, elegance, and a well-timed wink. In short, the song claims that women rule the world, not through force, but through irresistible charisma that men happily – even proudly – surrender to.
