Abstract
It is said that the logothetes system in the central administrative departments characterized Byzantine government. δ λογοθετηζ του γενικου and ο λογοθετηζ του στρατιωτικου as financial minister and ο λοιοθετηζ του δρομου as a minister of the foreign affairs played an important role. The logothetes as a financial minister were organized between 610 and 662, and ο λοΥοθετηζ του δρομουwas organized between 680 and 759.
A particularly important and characteristic mark of the establishement of the financial logoehetes was the concentration of the military and civil authority in the financial affairs under the command of ο σακελλαριοζ. This concentration was carried out as one of the reconstructive policies of the Roman Empire which had been ruined economically and financially since the death of Justinianus I.
