Phokas (‹See Tfd›Greek: Φωκᾶς, translit. Phōkâs) or Phocas (Latinized), feminine form Phokaina or Phocaena (Φώκαινα, Phṓkaina), was the name of a Byzantine aristocratic clan from Cappadocia, which in the 9th and 10th centuries provided a series of high-ranking generals and an emperor, Nikephoros II Phokas (r. 963–969). Its members and their clients monopolized the high-command positions of the Byzantine army for much of the 10th century and led the successful Byzantine offensive against the Arabs in the East. As one of the leading families of the Anatolian military aristocracy, the Phokades were also involved in a series of rebellions that laid claim to power and challenged the emperors at Constantinople. Their power was eventually broken by Basil II (r. 976–1025), and the family declined in importance after the 11th century.
