Helen of Sparta was the cause of the war between Greece and Troy. She married Menelaus and was believed to be the most beautiful woman in the world .
Aphrodite promised Helen to Paris, prince of Troy.
Aphrodite made Helen fall in love with Paris and they eloped by ship to Troy
This made Agamemnon, menelaus's father angry and he organized a military expedition to troy to get Helen back. He sacrificed his own daughter, Iphigenia to Artemis, for win favourable winds for the journey.
For around 10 years, the Greeks attempted to attack Troy, but the city was heavily fortified and held out.
Then Odysseus, the king of Ithaca thought of a trick for them to seize Troy. they built a huge wooden horse, left it outside the city then sailed away.
The trojans brought the horse into the city, thinking it was good luck. At night, the Greek soldiers hiding inside, opened the city gates from the inside and let their army in. they destroyed the city and won the war.
