Who started the term "Christian"?

It is recorded, in the Bible in Acts 11: 19-26 and in historical records covering the rule by the Roman emperor Trajan (ruled from C.E. 98 until C.E. 117) and the Roman governor of Antioch, Pliny the Younger, that the term and label "Christian" was first used.

Did the followers of Lord Jesus start at this time, after some 60+ years after the resurrection of Lord Jesus to refer to themselves as "Christians"?

Was it instead the Romans in Antioch lead by the Roman Antioch governor Pliny the Younger that started to refer to the followers of Christ as "Christians"?

Up until this time, the true followers of Lord Jesus refered to themselves as 'disciples' of Lord Jesus or as followers of 'The Way' (i.e. the 1 True Way). Why would they, after some 60 years, start to refer to themselves as "Christians"?

It is recorder that the governor of Antioch, Pliny the Younger, wrote to the emperor Trajan asking what to do with these “ Christians". It seems much more likey that the Romans created this label as a means to identify the followers of Christ as a fringe religious group that did not believe in also bowing to Caesar as a god.
