Starting in 499 BC, a series of conflicts and battles rose between the Achaemenid Empire of Persia and Greek city-states. This event known as the “Persian Wars” began when Athens agreed to come to the aid of the Greek speaking city-states on the coast of Asian Minor. As these city-states rebelled against the great and powerful Persian empire, the Persians grew bitterly toward the Athens. After nine years, Darius the Great, the fourth king of the Persian Achaemenid Empire launched an attack against the Greek Mainland. This was known as the “Battle of Marathon”.As the Athenian army was only a fraction of the side of the Persians, the Persians won this battle. This led to Greece under control of the Persians.
