The Belville theme which was introduced in 1994 and later discontinued in 2009 was created to appeal primarily to girls. While the sets revolved around the concept of the LEGO system it featured doll-like figures known as Belville Figures instead of regular LEGO minifigures. The Belville Figures featured multiple joints to make play more like normal doll play and were larger than minifigures. The Belville theme was the predecessor to LEGO Friends.
