I have a question about this sentence
Inspired by a revolt dating back to the 12th century,
against a ruthless count that used to drag young girls,
about to be married to his chambers,
the festival celebrates the people's victory and their freedom.

My question is what is omitted in front of "inspired by"
Is that As the festival is inspired by?
I really appreciate your advice
