The group was created in 1998 with three members: Andreas Lundstedt (born 20 May 1972, Uppsala, Sweden), Tess Merkel (born Therese Merkel, 18 April 1970, Nykoping, Sweden), and Annikafiore Kjaergaard (born 18 May 1971, Bjarnum, Sweden). Their first single, "Shine On", was successful in Sweden but it was with their second release, "Crying At The Discoteque", that they achieved success across Europe. Both singles appeared on their debut album Casino. Later editions of Casino contained a cover of the Human League hit "Don't You Want Me", which also was the album's third single.
In December 2002, Magnus Carlson (born 24 June 1974, Borås, Sweden) joined the group. The second album Alcazarized was released in Sweden in 2003, it became a big hit and got an international release in 2004.
In the autumn of 2004 Alcazar released "This Is The World We Live In". The track samples Diana Ross' 1980 number one "Upside Down" and uses lyrics from Genesis' 1986 single "Land of Confusion". Their follow-up single was entitled "Physical".
Alcazar released the album Dancefloor Deluxe in Sweden in August 2004 and in the winter of 2004 they released the Christmas single "Here I Am".

In May 2007 the band did a one-off performance in London at the legendary night club "G-A-Y" and invited their friend Lina Hedlund (born 28 March 1978, Hanebo, Sweden) to join them on stage. It all turned out to be a very successful combination and a few months later the "New Alcazar" was formed.
In January 2008 their first single "We Keep On Rockin'" was released. Music and lyrics by long time team member Anders Hansson. The single quickly turned into a hit and only a week after the release the single passed gold status in sales.
