In Greek mythology, how long did the Trojan War last?

kinda messed up Aphrodite was the one that gifted the kings sister in law. whyd the Trojans pay for it?

Marcy, I suppose you mean the Trojan war ended when the city of Troy was defeated following a very siege . This happened when the Greeks appeared to sail home leaving a gift of a great wooden horse . The Trojans took this inside the city unaware that Greek troops were hiding inside . After nightfall they emerged and let their comrades, who had feinted a return home but actually sailed back to Troy, into the city

Trojan war was defeated coz. of wooden Horse as a gift (but with soldiers inside it) so when the enemy was drunk time to attack
