Ever wonder why baby Jesus arrived in that Bethlehem manger at the exact moment that he did. It wasn’t a whim. In fact, God says the time was pre-appointed. So why this particular point in Roman history? No doubt God will explain personally someday, but from a purely practical viewpoint, it was nearly perfect.
Paul explained, in Galatians, that the Jews were held in protection under the law,
“But when the time had fully come, God sent his Son, born of a woman, born under law, to redeem those under law, (Gal.4:3-5 NKJV)

Actually, a lot of reasons.
First of all, Roman influence was pretty much at its height. At that point Rome ruled most of the United Kingdom as well as the rest of Europe, as well as much of what is now Arab territory. The kingdom was also at peace, and the roads were famous for extending throughout the empire, permitting relatively safe and unfettered travel thus, paving the way (pun intended) for news of the arrival of the promised Messiah.
And later, His crucifixion and resurrection.
Furthermore, the foundation laid by Greek philosophers paved the way for thinking about higher things and therefore set the stage for the gospel. (Paul used Greek philosophy as a springboard for the gospel in Acts 17).
And although in Rome the population spoke Latin, Koine (common) Greek was the unofficial language of the Empire and the language spoken for intercultural commerce,
