Welcome to Harry Potter Theory. Today we're looking at muggle/wizard affairs throughout history, starting as far back as 382 BC. 
When we crack open our history books, and take a look at famous events and conflicts between muggles and the wizarding world, you might be surprised at what you find.
Before the International Statute of Wizarding Secrecy, which was established in the year 1692, wizards weren’t exactly unknown.
Although, even at that time, many considered the concept of witches and wizards outlandish… There were plenty of people who had firsthand experience with members of the wizarding world.
In fact, in different corners of the world, at varying times, entire countries were swept into anti-magic crazes that threatened to destroy almost every magic-using man, woman, and child in their community.
Today, we’re going to take a look at some of these events, and their long-lasting legacy, as we discuss the history of muggle and wizard affairs.
If you think of the modern world, then the fact that Muggles and the wizards don’t intermingle is a foregone conclusion.  After all, the ministry of magic had worked tirelessly, for centuries, in order to keep their constituents a secret.  
But when we look back in time, to the earliest records, we find a very different landscape.
In the official history of the wizarding world, the earliest date documented is 382 B.C.  That’s the year that a Roman ancestor of Garrick Ollivander, the wandmaker from Diagon Alley in Great Britain, created their first branch in ancient Rome.  
There’s more than a 1,000 year gap between that date, and the next listed event in official wizarding records.  So, if we were to try and guess what happened, and how the wizarding world might have interacted with muggles of that time, we’ll have to rely on our detective skills.
