Around the year 1200 BC a powerful Greek army crossed the Egean Sea to destroy the city of Troy. 
Homer sang those acts in the Iliad, considered legendary and unreal during centuries. However, in the XIX century Heinrich Schliemann discovered the remains of Troy and demonstrated that its destruction for a Greek coalition had existed.

The Iliad describes the war between a powerful Greek coalition and Troy&allies, both sides helped by different faced Gods. The cause of the war is the kidnapping of Helen, wife of Menelaos king of Sparta, by Paris son of Priam king of Troy. The modern historians and archaeologists believe the true reason was to destroy the great economic power of Troy. This city was located in the Dardanelles Straits, for what blocked and monopolized the marine commercial route toward the Black Sea.

The war lasted 10 years. The first 9 years there were constants attacks and lootings of the Greeks to the trojans or allied cities of the West Asia Minor coast. These lootings weakened a lot to the trojan coalition. The tenth year takes place the definitive assault to the city of Troy. The powerful Greek army is formed by about  90.000 or 100.000 men, embarked in more than a thousand ships (The great quantity of troops produced many problems to the Greeks that passed hunger and plagues during the long siege) and it is compound for troops of different Greek states, commanded by its kings or generals. The commander in chief is Agamemnon, king of Mycenae. The trojans are less numerous. Their chief is Priam King of Troy, old man. The commander in the battle is his son Hector, great fighter. They are also helped by allied troops from different places of Asia Minor, and until of the Greek peninsula, as the trhacians.

To the head of the troops there are famous leaders and heroes, some of them demigods (children of a god and a human). According to the Iliad the gods of the Olympus participate actively in the battle, and each side has a group of gods that help him, while the chief and more powerful of all, Zeus, helps alternatingly to one or another side, according to his state of humor.
