Input: What was the last time he traveled to Mansfeld?, Context: Luther's final journey, to Mansfeld, was taken because of his concern for his siblings' families continuing in their father Hans Luther's copper mining trade. Their livelihood was threatened by Count Albrecht of Mansfeld bringing the industry under his own control. The controversy that ensued involved all four Mansfeld counts: Albrecht, Philip, John George, and Gerhard. Luther journeyed to Mansfeld twice in late 1545 to participate in the negotiations for a settlement, and a third visit was needed in early 1546 for their completion.
Output:
early 1546
