There were two wealthy families in the city of Verona, Italy and they absolutely hated and despised of each other. They fought and attacked each other so much the prince made a law that the next person to break the peace would have to die.
Romeo and Juliet (two starcross'd lovers) meet at a ball and they instantly fall in love. Through conversation they realise they are from the opposing sides. They didn't care and shared a kiss.
Juliet was declaring her love for Romeo believing she was alone but Romeo heard her and he declared his love for her as well and then they decided to get married.
Romeo was celebrating his wedding with his friends Benvolio and Mercutio and Tybalt was angry so he killed Mercutio and Romeo avenged his death by killing Tybalt.
Juliet had a plan to get away from Verona. She pretended to be dead and Romeo wasn't aware of the plan and killed himself with a potion because he wanted to be with Juliet in death. Juliet wakes up to find Romeo dead and kills herself with her dagger so she can be with Romeo in death.
Here lies Juliet
The two familes are brought down in grief and decide to reconcile their hatred and become freinds rather than foes.
