The Feud Between the Montanas and the Callaways

The feud between the Montanas and the Callaways was a long-lasting war that had gone on for many generations between the Montana and Callaway families of witches. None of the current descendants know how it started.

The two families would fight each other until one side was eradicated. The feud eventually ended with intervention from the Charmed Ones in 2003.

Background
Members of these two families had been at war for many generations. Other magical beings, such as whitelighters or muses, had tried to help end the feud peacefully, none of which worked. Since both families consisted of powerful witches, neither side came out on top.

The Truce
In the modern generation, one member of either family, Richard Montana and Olivia Callaway fell in love and decided to marry in hopes of ending the feud peacefully. Unfortunately, Olivia was accidently killed in a crossfire by Steve Montana in 2002. This was covered up and everyone believed she was killed by one of her own. A truce was evoked and neither side bothered the other for a while. Olivia's spirit, however, became vengeful due to the pain of losing her love, and decided to make both families fight once again.

The Ending of the Feud
Paige Matthews was inadvertently brought into the mix when she took a temp job as Grandma Callaway's caretaker. Olivia attacked her with a plasma ball and later killed Richard's father, Benjamin. The Charmed Ones suspected a spirit to be involved in breaking the feud and had both families come to their house to perform a seance. Olivia's spirit clarified her death, then possessed Paige just as the fight broke out in the Montana Estate. Though no one died, Richard was badly hurt and Olivia orbed him to her grave when she assumed he was dying. This finally made the families realize how pointless their feud was and ended it by helping the Halliwells find Paige, Richard and Olivia. Paige then convinced Olivia to let go of her pain and Richard so that she may leave Limbo.
