Why was Lepidus stripped of his triumviral power in 36 BCE?
He was executed for treason after the Battle of Actium
His legions defected to Octavian after Lepidus tried to seize Sicily for himself✓Bonne réponse
He voluntarily retired to devote himself entirely to religious duties
The Senate voted to abolish the triumvirate before its term expired
Explication
When Lepidus tried to claim Sicily and challenge Octavian's authority there in 36 BCE, his own soldiers abandoned him for Octavian, leaving him powerless and stripped of his triumviral rank. He was not executed, his retirement was not voluntary, and the Senate did not independently dissolve the triumvirate at that point.
