1/4 Thaler - August

Brunswick-Wolfenbüttel's August the Younger — Duke from 1635 until his death in 1666 — was among the most prolific book collectors in seventeenth-century Europe, amassing a library of over 130,000 volumes that formed the nucleus of today's Herzog August Bibliothek in Wolfenbüttel. This 1643 issue falls squarely within the Thirty Years' War, which devastated much of the German territorial patchwork around him, though Brunswick-Wolfenbüttel navigated the conflict with relative diplomatic dexterity.

Welter 836 is well-documented within the series. The 1643 date places it two years before the Congress of Westphalia opened.
