Praejecta or Praiecta (Greek: Πραιέκτα) was sister to Byzantine emperor Justin II and a niece to Justinian I (r. 527–565).
Praejecta was a daughter of Vigilantia and Dulcidio (or Dulcissimus), respectively the sister and brother-in-law of Emperor Justinian.
[2] In 545, as the situation in Africa had gotten out of control following the death of Solomon and his replacement by his incompetent nephew Sergius, Areobindus, although having no prior military experience, was dispatched there with a small force.
[5][6] After Guntharic's assassination by the Armenian Artabanes in May and the restoration of Byzantine imperial rule, Praejecta rewarded him with a large sum of money and became engaged to him.
[5][7] Artabanes was enraged by this affair, and it contributed to his involvement in the failed conspiracy to overthrow Emperor Justinian in late 548.
