 Pepin feigned illness as he plotted with "certain leading Franks" to overthrow his father.When the plot was discovered, Einhard writes that Pepin was tonsured and sent directly to the monastery of Prüm.In his paper "Pipinus Rex" historian Carl Hammer points out the disparate attention Einhard gives to Pepin's revolt, arguing, "he gives it priority over his account of the evidently more widespread and possibly more dangerous rebellion of 785/6."
