 As early as the late 1380s and early 1390s , Isabeau demonstrated that she possessed diplomatic influence when the Florentine delegation requested her political intervention in the Gian Galeazzo Visconti affair . Orléans and the Duke of Burgundy were in the pro @-@ Visconti faction while the anti @-@ Visconti faction included Isabeau , her brother , Louis VII , Duke of Bavaria , and John III , Count of Armagnac . At that time Isabeau lacked the political power to effect change . Some years later , however , at the 1396 wedding of her seven @-@ year @-@ old daughter , Isabella , to Richard II of England ( an event at which Charles attacked a herald for wearing Galeazzo 's livery ) , Isabeau successfully negotiated an alliance between France and Florence with Florentine ambassador Buonaccorso Pitti .
