The principal cause of the sack was the delay in payment due to the soldiers by
Philip II of Spain, who had recently declared bankruptcy. Bankers refused to perform the transactions the king of Spain asked of them until they had reached a compromise. Case in point, the transfer of the troops' salary from Spain could not be performed by letter of exchange (the 16th-century equivalent of a money order). So, the Spanish government had to transfer the actual cash by sea, which was a much more expensive, slow, and dangerous operation: for instance, in 1568, 400,000
florins intended as payment to the troops had been seized by the government of
Elizabeth I when ships containing the florins sought shelter from a storm in English ports. Spanish soldiers, angry at fighting without rest or pay against rebels, had already sacked
Zierikzee and
Aalst, causing the fifteen loyal provinces (
Holland and
Zeeland were in the hands of the rebels) to come together in
States-General to remove the
mercenaries from the Netherlands. It was an ordinary procedure with the soldiery then, and their procedure was invariable. Without breaking their celebrated discipline, they would choose a new leader, or
Eletto, from their number and march in perfect order under him to whatever their target was. In this instance, the Spanish soldiers decided to find their belated pay for themselves by looting Antwerp. == Events ==
