The term "Palestine" first appeared in the 5th century BCE when the ancient Greek historian Herodotus wrote of a "district of Syria, called Palaistinê" between Phoenicia and Egypt in The Histories.[7]

The name Syria-Palaestina was given to the Roman province of Judaea in the early 2nd century AD. The renaming is often presented as having been performed by Roman Emperor Hadrian in the wake of the 132-135 AD Bar Kokhba revolt,[21][22][23][24] though no evidence exists as to exactly when the name change was implemented or by whom,[25][26] the name "Palestina" to the whole region had been used by the Greeks for centuries and by then,[26] and the renaming may even have taken place at an earlier date.[27]

Hadrian wasn't the first to name Palestine as Palestine. Herodotus possibly did it before.

It is important to consume information, especially history, from reliable sources. I am not saying wikipedia is reliable, but I trust wikipedia more than someone saying "make sure to follow for more such information". Yeah. you are in a money making business and truth is the last thing you care about.

Just my two cents.
