Turkish aid (in German Türkenhilfe)

Hungarian and Turkish castles
It was aid paid by the orders of the Holy Roman Empire, the Austrian hereditary provinces, Bohemia and Moravia and Silesia in order to subsidise border defence in Hungary against the Turks in the 16-17th century. Since Hungary was protecting these countries from the Turks, in return, they took a financial role in the defence by regularly submitting yearly assistance (as a kind of tax). The paying of border fortress soldiers, the maintenance of border fortresses and the prevention of the Turkish conquest would not have been possible without these financial contributions.
