Last week, Broadway actress Aisha Jackson became the first black actress to portray Frozen‘s Anna on Broadway.

Jackson, who is the understudy to Patti Murin, the main actress for the role, debuted on Thursday.

This marks a historic moment for Broadway, which still has diversity issues when it comes to casting.

Typically roles are not race-bent, with Toni Braxton portraying Belle being one of the only other instances of a traditionally-white Disney princess being black on the stage (though Anna, technically, is not a Disney princess).

Co-star Jelani Alladin, shared a post on Instagram. “Tonight we made #blackhistory with @gifted2sing playing Princess Anna in Frozen! I am so blown away by the professionalism and talent of this company! Wow! #wakandaforever CONGRATS AISHA!!!!!! #frozen#blackbroadway #kristanna.”

Last night was simply amazing. The love and support from my cast, crew, orchestra, management, producers, agents, family, and friends was, and still is, overwhelming. Y’all know how to make a girl feel special. THANK YOU SO MUCH!! I dedicated last night’s show to my two angels, Vaughn and Amy! And to all the little chocolate princesses that don’t always get to see themselves onstage. I hope I made you all proud!!”
