Today we learned something new about Star Wars' beloved Princess Leia. Apparently, not only did she earn her PhD before becoming a general in the Rebel Alliance, she did so at the age of 19 years old.

This important detail of Leia's life was pointed out by Twitter user Becca Harrison, who discovered mention of it in Carolyn Cocca's 2016 book Superwomen: Gender, Power, and Representation.

The book cites George Lucas' 2004 commentary for Star Wars: A New Hope, where he mentions that Leia was busy getting her doctorate while Luke was still working on a farm. "She's like a very sophisticated, urbanized ruler, a senator, so she's a politician. She's accomplished, graduated, got her Ph.D. at 19 and she rules people."

This news may seem inconsequential, but it adds further depth to Carrie Fisher's iconic Leia Organa. She's an expert politician, a beautiful princess, a powerful general, and now a well-educated woman.

Following Fisher's death in December 2016, Star Wars: The Last Jedi will be the final appearance of the Leia Organa character.
