Mittenwald, along with Garmich-Partenkirchen to the west, was acquired by the Prince-Bishopric of Freising in the late 14th century and the "crowned Aethiopian" head that is part of Mittenwald's coat of arms recalls that 400-year association that ended when the Prince-Bishopric was secularized in 1802-03 and its territory annexed to Bavaria.
Mittenwald's location as an important transit centre on a relatively low (and therefore predicable) transalpine route has been a defining feature of the area for at least two thousand years: during the sixteenth and seventeenth centuries traffic was boosted by large treasure trains sent regularly from Spain to pay troops in the Netherlands, the more conventional sea route having been rendered unreliable by the (usually) discreet but effective sympathy with which the English Protestant establishment favoured the Spanish king's rebellious Dutch subjects
