1 Thaler - John Frederick I

John Frederick ruled Württemberg from 1608 until his death in 1628, a reign consumed almost entirely by the catastrophe of the Thirty Years' War. By 1624, Imperial and Catholic League forces were pressing deep into Protestant territories, and Württemberg's finances were under severe strain — the duchy would be occupied by Tilly's forces just a few years later, in 1634, triggering a population collapse from which the region took generations to recover. That this thaler was struck at all in 1624 reflects a deliberate assertion of ducal authority at a moment when that authority was increasingly precarious.
