 Although Charles' reign is no longer considered transitional in its feudal developments, it is seen as a transitional period in the spread of the existing system of vassals and "precaria" land rights.Due to Charles' continued military and missionary work, the political systems that existed in the heartlands, Austrasia and Neustria, officially began to spread to the periphery.Those whom Charles appointed as new nobility in these regions, often with lifetime tenures, ensured that Carolingian loyalties and systems was maintained across the kingdoms.
