Who was involved in Justinian becoming emperor?

Answer 1

Justinian I (or the Great) was the maternal nephew of Justin I, the previous emperor. Justin adopted Justinian, making him his heir. Justinian was also his closest confidant and was made associate emperor in the year when Justin died. It is thought that Justinian was a virtual regent long before this because Justin became senile. However, there is no conclusive evidence. Still, at the end of Justin's reign, Justinian was a de facto ruler. when Justin died, Justinian became sole ruler.
