The Spice Girls use the phrase Girl Power and many fans thought that they were the first ones to use this phrase. But this is not so...

One of the earliest uses of the phrase "Girl Power" was in 1987 by a London based 'capella' all-girl group called 'Mint Juleps' in a song entitled 'Girl to the Power of 6'. It was subsequently used in a fanzine by punk bandBikini Kill. The phrase is sometimes spelled as "grrrl power", initially associated with Riot Grrrl.^[1][2]

"Girl power" was later utilized by a number of bands during the early 1990s, such as the Welsh indie band Helen Love^[3] and the Plumstead pop-punk duo Shampoo,^[4] who released an album and single titled Girl Power in 1995.
