 In 1128, in concluding a war with his son-in-law, Count Bernard IV of Melgueil, William extorted a promise that the coinage would not be debased.William himself controlled the mint, however, and in 1130 he had to agree not issue any coinage on his own authority, but only with the approval of the count.These agreements were confirmed in 1132, 1135 and 1145–46.
