I have never been able to pinpoint the album/era that is considered to be Madonna's peak because she's had a lot of highs in her career.

When exactly was her peak?

Her absolute peak was on the True Blue era, but she kinda repeaked with Ray Of Light and this was consistent until Hard Candy.

True Blue / Vogue / The Immaculate Collection / Like a Prayer / Blond Ambition


Idk exactly.

True Blue

Bitch I'm Madonna

Vogue was her peak in the US commercially. Critically ROL was her peak in the US.

this from 1986 to 1991.

True Blue > LAP > Vogue/The Immaculate Collection > Blond Ambition Tour

True Blue

Sticky & Sweet Tour

edit: because of the superbowl

Im too young to answer.

The mid 80s (Like A Virgin & True Blue) were when she was at the highest point of her career.

1984 - 1991 is her peak and the biggest peak any female artist has ever had tbh. Her success and impact during those 7 years are mindblowing

This. I would add Ray of Light; the critic were feeding out of her hand during that era.

Commercial peak is True Blue

Creative peak is Erotica

True Blue - I'm Breathess (Vogue) eras

She has way too many peaks so I don't know....

Her looks went viral and she became the IT girl during the Like A Virgin era. peak of her hype.
True Blue era had the statistics but it was certainly riding on the hype of LAV. peak of her popularity.
Vogue/Blond Ambition was her most iconic moment. peak of iconicity.

(ROL was a huge success but Shania/Celine/Britney were all outselling her. it was a comeback but not a peak)

COADF~S&S Tour was her last peak. She gained enough momentum from ROL/Music and smashed the world with one of her biggest hits Hung Up. She was literally on top of the world in late 2005. COADF was also the last pop girl album to sell over 10M until Gaga happened.
