Khalid ibn Yazid (خالد بن يزيد بن معاوية; c. 665 CE – 704 CE) was an Umayyad prince, a brother of Muawiyah II who was briefly caliph. Prince Khalid lost the chance of inheriting the title, but took an interest in the study of alchemy, in Egypt, facilitating translations into Arabic of the existing literature. It is to this Khalid that later allusions to Calid rex (King Calid) refer.
