The Emperor Caius gave the Jewish King Agrippa I the "ornamenta praetoria" (praetorian rank, without the actual office).
The Emperor Claudius then gave the same Agrippa the "ornamenta consularia" (consular rank) and gave his brother praetorian rank.
In 75 AD his son Agrippa II was given praetorian rank.
Another relative, Julius Alexander, was consul after receiving part of Cilicia from Vespasian in 72AD.
His son Julius Agrippa was quaestor of Asia and another relative (apparently a great-grandson of King Herod the Great), Julius Alexander Berenicianus, was consul and proconsul of Asia in 132AD.
My question is - what would be necessary for one of these men, or one of their family, to become Emperor?
If men of Jewish blood could reach the consulate, is there any chance a man of Jewish faith would be able to make the jump from consul to Emperor?
And if so, what would this result in? Forcible conversions? Civil war? Prompt dethronement?
