Writ of Holy Roman Emperor Louis IV [Present-day Germany]: “Louis, the Bavarian (‘Ludwig der Baier’) confirms [in writing] that he has owed his brothers-in-law, Duke Henry, Otto, and Henry [of Bavaria] 20,000 Mark silver, for which he had prescribed them Weissenburg, Neumark, and the Jews of Regensburg: now, however, after he has lost Neumark […] he pledges to them Weissenburg and the Jews of Regensburg for 12,000 Mark and [the Jews of] Launigen for 8000 Mark.” [Researcher’s note: The above is a translation of a German summary of the old original text which can be found in Oefele’s Rerum Boicarum Scriptores (Volume II).]
