Answer:
The Trojan Horse is a story from Greek mythology, which tells of the Trojan War and the siege of the city of Troy. The war was fought between the city of Troy and a coalition of Greek states, led by King Agamemnon of Mycenae. The cause of the war was the abduction of Helen, the wife of King Menelaus of Sparta, by Paris, prince of Troy.
After a 10-year siege, the Greeks were unable to enter the city of Troy, due to its strong walls. The Greeks then resorted to a clever trick. They built a large wooden horse and left it outside the city gates, pretending to sail away. The Trojans, thinking the horse was a peace offering, brought the horse inside the city walls. That night, Greek soldiers hiding inside the horse emerged and opened the gates, allowing the rest of the Greek army to enter the city and defeat the Trojans.
