In Slavery in Árpád-era Hungary in a Comparative Context , Cameron Sutt examines servile labour in the first three centuries of the Hungarian kingdom and compares it with dependent labour in Carolingian Europe. Such comparative methodology provides a particularly clear view of the nature of dependent labour in both regions. Using legislation as well as charter evidence, Sutt establishes that lay landlords of Árpádian Hungary frequently relied upon slaves to work their land, but the situation in Carolingian areas was much more complex. The use of slave labour in Hungary continued until the end of the thirteenth century when a combination of economic and political factors brought it to an end.
