What is the purpose of the Capulet and Montague families feud in Romeo and Juliet?

Question

Why did Shakespeare decide to make the two families rivals? What impact does this have on the play?

Update:

No, I have read it. but what is the meaning behind it.. it's so unnecessary since their feud isn't even legitimate.

Answer 1

Have you read the play? The plot wouldn't make sense if the families liked each other and had barbecues together every Sunday. Then there would be no reason for them to stay apart, no reason for Romeo to get in a duel with Tybalt and kill him, and no reconciliation at the end.

Answer 2

it is the classic tragedy of two lovers who cannot be together because of social constraints. if you refuse to read the play, at least read the cliff notes or watch a modern day movie about it. everybody should know the story of romeo and juliet.
