Short answers, pulled from the story.
The Disney Renaissance comprises ten feature films released between 1989 and 1999: The Little Mermaid, The Rescuers Down Under, Beauty and the Beast, Aladdin, The Lion King, Pocahontas, The Hunchback of Notre Dame, Hercules, Mulan, and Tarzan.
The Renaissance was prompted by competition from Don Bluth's animated productions and the influence of Studio Ghibli films by Hayao Miyazaki. The commercial success of Who Framed Roger Rabbit in 1988, produced with Steven Spielberg, also restored executive confidence and public appetite for theatrical animation.
The Lion King, released on the 24th of June 1994, earned $968 million worldwide and remains the highest-grossing traditionally animated film in history.
Beauty and the Beast was the first animated film ever nominated for the Academy Award for Best Picture, a distinction it held as the sole nominee in a five-film category for the entire span from 1944 to 2008. It won two Academy Awards, for Best Original Score and Best Original Song, and was the first animated film to earn $100 million at the US box office.
Howard Ashman and Alan Menken wrote the songs for The Little Mermaid, Beauty and the Beast, and contributed songs to Aladdin before Ashman's death. Tim Rice completed Aladdin with Menken, then collaborated with Elton John and Hans Zimmer on The Lion King. Stephen Schwartz wrote lyrics for Pocahontas and The Hunchback of Notre Dame, while Phil Collins wrote and performed the Tarzan soundtrack.
The Renaissance's success prompted major film studios to create new animation divisions, including Fox Animation Studios, Warner Bros. Feature Animation, and DreamWorks Animation, all aimed at producing Disney-styled musicals. Robin Williams's performance as Genie in Aladdin is widely credited as the reason other studios began casting major celebrities as voice actors in animated films.
