Context: The Giudicati (4 Kingdoms of Sardinia) stand out in medieval Europe because they developed non-feudal state structures at a time when feudalism was spreading across the continent.

Unlike feudal monarchies built on personal vassalage, each giudicato operated through a surprisingly centralized and bureaucratic system rooted in late Roman and Byzantine administrative traditions.

The judge ruled as a sovereign executive, but his authority was balanced by assemblies such as the Corona de Logu, a council of nobles, clerics, and local leaders that could advise, confirm succession, and influence major policy decisions.

Power was further distributed through territorial districts (curadorias) administered by curadores, officials who resembled provincial governors rather than feudal lords.

This structure meant that, rather than a web of personal loyalties, Sardinia’s medieval states functioned as proto-institutional polities—closer to early bureaucratic kingdoms than to the feudal societies of contemporary Europe.
