He comes to power, his father was king of Macedon, but then his older brothers die. He becomes, it's actually his nephew, who is heir to the throne. He becomes regent for his infant nephew, which means he has the power temporarily, but then he actually takes full control and becomes king of Macedon, or Mac-a-don, as it's often pronounced, in 359 BCE. And what he then goes off about doing is taking over most of the Greek city-states, and eventually he's able to unify most of the Greek city-states. And you can see on this map here, which I got from Wikipedia, this is a little bit of information about the map, you can see how he expanded his empire over time. That, remember, 359 BCE, he becomes king of Macedon. In 352, he's moving into Thessaly.
