An ISIS defector once said Baghdadi liked having a sense of mystery around him.
"He would only introduce himself to top-level commanders. The minor ones, he did not introduce himself to. But what was interesting was that in a large group, no one was sure which person in the room was really him. He wanted it to be confused," he told Newsweek.
Baghdadi played a role in Syria's civil war too
By expanding ISIS to Syria, Baghdadi also played a role in the country's civil war to remove President Bashar al Assad from power.
In 2014, ISIL announced itself as a "caliphate", a move that invited criticism from the Muslim world and historians.
Unhindered by ire, Baghdadi kept doing his job, planning several terrorist attacks across the globe and killing thousands.
After ISIS fell, Baghdadi asked fighters to remain hopeful
A few months ago, when the US announced that most of the territories have been freed from ISIS' clutches, questions were asked about Baghdadi's whereabouts.
In a clip released in April, he purportedly asked fighters to not lose hope and remember what they are battling for.
But with the demise (?) of the dreaded terrorist, ISIS' heydays have come to an end, for good.
