The Cullens technically win since there was no fight as it was proven by Alice appearing with another half human/vampire and showing that they can develop and exist safely without exposing the human world to the supernatural world.
However, there is a constant feud between the covens as the Volturi feel threatened by the Cullens as they are the next largest coven to exist, and most of them have truly powerful talents. This suggests that the Volturi will continue to seek out any reason to destroy the Cullens as to maintain their power in the vampire world.
The villain is/are the Volturi as they come to fight with Bella and the Cullens because of the half human/half vampire baby, Renesmee...
In the book, The Volturi try and kill Bella's child because it is immortal, in the film Breaking Dawn Part 1, Bella's heart stops after she gives birth and the only people that fight are the Vampire Coven, Cullen family, and the Wolf Pack, except Jacob, Seth, and Leah help the Cullens. And Bella becomes a newborn at the end when the Cullens win.
***SPOILER ALERT***Bella turns into a vampire and her baby, Renesme, is a half vampire half human creation. Jacob imprints on her. Also, the volturi come for her baby and Bella has a special power, a protective shield. There is a major fight between many vampire clans that join with the Cullens to fight the Volturi.
Bella, Edward and the volturi. The volturi wants Bella to change into a vampire. It is actually not a war. But it is kind of a fight or a conflict between them.
The volturi want to fight the Cullen family because of renesmee ( daughter of Bella and edward ) also because Bella is not a vampire and she knows to much about vampires. hope this helps x
Yes, the Volturi leave the Cullens and the werewolves alone in Breaking Dawn right after the almost-fight. Irina(one of the sisters living in Denali) sees Renesmee with Bella and Jacob and thinks that she is with an immortal child which killed her mother. So Irina goes to the Volturi and tells then what she seen with the Cullens.Alice sees the Volturi coming and she leaves the Cullens without an explanation, only telling them to get all of the wittnesses they can possibly get, to show through their mind that Renesmee is not immortal. When the Volturi finally meet with the Cullens nearly a month later, they see in the wittnesses minds that Renesmee is not immortal, and Alice comes back with a half-vampire, half-human child back to show the Volturi that she will stop growning in about 10-18 years of life. After the almost-fight meant to eliminate the Cullens and the wrewolves who had also came to wittness, they decide to leave in peace-for now...
when the volturi come in breaking dawn everyon gets ready for a fight. the cullens contact all ther allies. the volturi come to destroy renesmee but they don't succeed because Bella uses her 'shield' to stop them by projecting it around everyone. this way Jane and alec cant touch them. in the end the voltri go away and the Cullen's side wins. no one gets hurt of dies.

Nobody really fought in Breaking Dawn although the Volturi and the Cullen family were going to fight but they proved that no one would have to fight.
Bella did not kill any of the volturi members, although she wanted to kill Jane if it came to a fight.
Bella and Edward get married. Bella gets pregnant. The baby is killing her and sucking the life out of her. The baby eats its way out of Bella. Edward turns her into a vampire. The baby's name is Renesme Carlie Cullen.
If I were to list all the people, it would be impossible. But the two groups of people that fight against each other are the Volturi, who fight against the Cullens and all the vampires that the Cullens convince to help them.
