The history of the Goths, is, well, an entire story on its own, and one that can't fully fit here. But here are the basics.
There really isn't a whole lot known about the origins of the Goths; as explained by Live Science, as best we can tell, they might have originated up near Scandinavia before traveling south and having a series of run-ins with the Roman Empire. Although, "run-ins" might be putting it lightly. The Romans actually referred to them as barbarians, and the history between the two groups was contentious at best, marked with raids and conflict across multiple centuries. And the Goths were the ones to sack Rome in the 5th century, so, you know, there's also that.
This tumultuous relationship with Rome is where Greece comes into the picture, seeing as how, at the time, Greece was under the rule of the Romans. The Goths started leading invasions into Greece during the middle of the 3rd century, only to be met by Roman forces in battle (one of which took place in Thermopylae, which might sound familiar if you've heard of the 300). One of those invasions eventually went after Ephesus, which, under the Romans, had become the capital of that region, according to the World History Encyclopedia. In that particular campaign in 267 A.D., the Goths also attacked the Temple of Artemis, most likely destroying it (or at least, plundering it). From there, things were set to really go south.
