Brunswick-Wolfenbüttel operated under joint rule from 1685 when Anthony Ulrich was elevated to co-regent alongside his elder brother Rudolph August — an arrangement that produced the relatively unusual dual-portrait coinage of this period. The brothers governed in persistent tension; Rudolph August preferred withdrawal from court life while Anthony Ulrich drove the duchy's cultural ambitions, funding an opera house and positioning Wolfenbüttel as a minor rival to Dresden.
The Mariengroschen denomination takes its name from the Virgin Mary, a holdover from Hanoverian and Lower Saxon minting traditions dating to the fifteenth century. Rudolph August died in 1704, ending the joint reign and the coinage type with it.
