Even in my SCA days, the only women crusaders (mulieribus crucesignatis) I ever had heard of were the womenfolk of the king of Jerusalem’s family, and Queen Eleanor’s party Amazons.
But Pope Innocent III wrote to the Bishop of Canterbury a letter known as “Quod super his,” which says that women could go to the Holy Land with their fighting husbands if they wanted, or lead bands of trained warriors at their own expense.
There seems to be a lot of talk about this letter on the internet, but not so much in the way of actual transcripts. Sigh. But anyway, it’s in Patrologia Latina 216, 1261-2.
“But concerning the women, we believe this ought to be heeded — that those who will not stay back may follow their men who are going. Surely the rest (except those perchance who are rich, who may lead warriors at their own expense) may redeem the [Crusading] vow they have vowed by having diligently influenced others to help the Holy Land, each according to their own means.”
