Apart from the slavery, the erection of hereditary nobility and recognition of noble titles raised controversies. Because the King's original charter to the eight proprietors for Carolina prevented the proprietors from granting titles already in use in England, such as Earl or Baron, they created two new titles, cassique and landgrave, that would be passed down from father to son. Those nobles were granted privileges such as being tried only in Chief Justice's Court and being found guilty by a jury of their peers. (Article 27) The Constitutions introduced also a hereditary serfdom system, the members of which were called leetmen, in addition to slavery.
