Alexius' grandson
Manuel I Comnenus continued to grant land to the aristocrats, but also extended
pronoiai to aristocratic officers in the army, in place of giving them a regular salary.
Pronoiai developed into essentially a license to
tax the citizens who lived within the boundaries of the grant (the paroikoi). Pronoiars (those who had been granted a
pronoia) became something like tax collectors, who were allowed to keep some of the revenue they collected. This idea was not completely new; centuries before,
Heraclius had reorganized the empire's land into military districts called
Themata. Under this system, military officers (
strategoi) ran each district and collected rent from the peasants who farmed the land. However, the
paroikoi, under either the
theme or
pronoia system, were not
serfs as peasants were in the
feudal system of western
Europe. They owed no particular loyalty or service to the strategos or pronoiar, as in both cases the emperor was still the legal owner of the land. The pronoiar was most likely not even a native of the land he had been granted. The size and value of the
pronoia, the number of
paroikoi, and the duties owed by them were recorded in
praktika. A pronoiar would likely be able to collect trade revenue and part of the crop harvested on the land, and could also hold hunting rights and transportation rights. A praktika also recorded the duties owed by the pronoiar to the emperor. If necessary, the emperor could request military service, although the pronoiar could not force his taxpayers to join him. Pronoiars were often reluctant to give military service if they lived a prosperous life on their grant, and they had some autonomy if they chose not to serve. If they could gain the support of their taxpayers, they could lead rebellions against the empire, but these were not as dangerous as rebellions in the capital, which Alexius' system could now more successfully avoid. Neither Alexius, Manuel, or the other 12th century emperors seemed to worry about provincial rebellions, seemingly assuming that a
pronoia grant would eventually appease a rebellious noble. During the
Fourth Crusade,
Alexius IV still thought this way, and granted
Crete to
Boniface of Montferrat, under the assumption that the Crusaders would go away if their leader had some land. ==
