ENThe article analyses the expenditures of the Lithuanian vice-treasurer Gabriel Kimbar, who managed the finances of the Grand Duchy of Lithuania in the place of the grand treasurer from 1662–to 1663. It was a tough period due to military confederations and the war with Moscow, which started in 1654 and resulted in enormous material and demographic losses. The reconstructed structure of treasury expenditures reveals that up to 75–80 per cent of funds were transferred for the payment of outstanding salaries and due gratuities to offi cers and soldiers in the analysed period. Another 10 per cent was used to reimburse debts to the treasury’s creditors. Very little money remained for other military expenses (e.g. fortress garrisons, war material purchases, and artillery maintenance). There was little expenditure on some areas crucial to the smooth running of the state, such as diplomacy, treasury administration or the postal service. Despite the very considerable outlay, it was still impossible to satisfy all the army’s claims. As Antanas Tyla’s research shows, similar trends continued in later years. Lithuania emerged from the era of the great wars of the second half of the seventeenth century as a financially inefficient state, utterly incapable of modernising its outdated structures. Keywords: finances, treasury registers, military expenditures, Lithuanian treasurer, diplomacy. [From the publication]
