1 Thaler - Louis IV

Louis IV of Hessen-Marburg ruled only the Marburg partition of Hesse, a territory created by the 1567 division that split the landgraviate among the four sons of Philip the Magnanimous. That partition proved a bureaucratic and dynastic headache for decades — the Marburg line itself died out in 1604 when Louis IV's brother Frederick died without heirs, triggering a bitter inheritance dispute between Hessen-Kassel and Hessen-Darmstadt that dragged well into the Thirty Years' War.

The Schütz III#497 reference places this among a small documented series from the Marburg mint's final active decades before the line's extinction ended independent coinage there.
