This chapter analyzes the earliest medieval evidence for the position of advocate. It argues that, rather than relying on top-down sources such as Frankish legal texts (capitularies) and the canons of Church councils, we need to focus on what named advocates are described as doing in eighth- and early ninth-century sources. Taking this approach, it demonstrates that advocates first emerged in the Frankish empire in the mid-eighth century and then proliferated rapidly under Charlemagne. Contrary to the standard argument that these Carolingian advocates were official, legal representatives for ecclesiastics at court, the chapter contends that – from the beginning – advocates were closely tied to the local territorial interests of monasteries and churches and frequently pushed the limits of their formal responsibilities.
