20 July - Alexander the Great birth anniversary

Alexander III of Macedon ( 20/21 July 356 BC – 10/11 June 323 BC), commonly known as Alexander the Great (Aléxandros ho Mégas), was a king (basileus) of the ancient Greek kingdom of Macedon[a] and a member of the Argead dynasty. He was born in Pella in 356 BC and succeeded his father Philip II to the throne at the age of 20. He spent most of his ruling years on an unprecedented military campaign through western Asia and northeast Africa, and by the age of thirty, he had created one of the largest empires of the ancient world, stretching from Greece to northwestern India.He was undefeated in battle and is widely considered one of history's most successful military commanders.

Alexander was born in Pella, the capital of the Kingdom of Macedon,on the sixth day of the ancient Greek month of Hekatombaion, which probably corresponds to 20 July 356 BC, although the exact date is uncertain.He was the son of the king of Macedon, Philip II, and his fourth wife, Olympias, the daughter of Neoptolemus I, king of Epirus.Although Philip had seven or eight wives, Olympias was his principal wife for some time, likely because she gave birth to Alexander.
