In 1765, it became "Gibbet Island," named after the tool used to hang pirates and convicts from trees on the island.
The executioners were ceaselessly at work with stake, sword and gibbet.
The Sarbadarids (so called from their motto Sar-ba-dar, Head to the Gibbet), descendants of Abd al-Razzak, who rebelled in Khorasan about 1337, enjoyed some measure of independence under twelve rulers till they also were destroyed by Timur (c. 1380).
Among the curious customs of Halifax was the Gibbet Law, which was probably established by a prescriptive right to protect the wool trade, and gave the inhabitants the power of executing any one taken within their liberty, who, when tried by a jury of sixteen of the frith-burgesses, was found guilty of the theft of any goods of the value of more than 13d.
The executions took place on market days on a hill outside the town, the gibbet somewhat resembling a guillotine.
