Princess Juliana (lived 1909-2004) was a Dutch Princess in the year 1940 and she is part of the WW2 Western Front mod (Deluxe version). She has the same abilities as an Abolitionist unit but she can't be built because she represents an individual person. Because it's the year 1940 and slavery has become a thing of the past and been emancipated and abolished for several decades its best to use Juliana's Incite Uprising ability instead.
