In the 12th century, a conflict arose between the inhabitants of Lavedan and those of the Aspe Valley for a theft of livestock; the result was the death of several Aspe people. The Bishop of Comminges, Bertrand excommunicated the Bigorre people who were repentant. They were sentenced to life imprisonment and to pay a yearly fine on the day of Saint Michel in the Church of Saint-Savin. It was regularly paid until 1789, and it was known as the "tribut des Médailles" of the medals.
