**Katherine Pierce**, born **Katerina Petrova** *(**Bulgarian**: Катерина Петрова)* was a witch of the Traveler sub-culture and a former main character of *The Vampire Diaries*. She was also the second-known Petrova Doppelgänger of Amara and a former vampire. She was the main antagonist of season one (mostly off-screen through John Gilbert's and Isobel's actions, as both were working for her in order to kill off the tomb vampires), and one of the main antagonists of season two, the second half of season four and the first half of Season Five. She was also the final antagonist of season eight. Katherine can be considered the main antagonist of the series overall due to being a major antagonist in the first, second, fourth, fifth and eighth seasons and all the antagonists that were a result of her actions.

In 1490, she was disowned by her father because she brought shame upon her family after giving birth to a baby girl out of wedlock when she was seventeen. She was forced to give the baby up for adoption and then was then exiled to England. She quickly assimilated into English culture and met two nobleman brothers, Niklaus and Elijah Mikaelson. At first, she was attracted to both men, but in time, she eventually learned that she was a Petrova doppelgänger and that Klaus was planning on using her as a sacrifice in order to break the curse that bound his werewolf side. She sabotaged his plan by running away with the moonstone, which bound the curse, and then tricked Rose into feeding her vampire blood so she could turn herself into a vampire. Because Katherine was no longer human, her blood no longer was a viable component of the ritual to undo the curse. Klaus was so infuriated with Katherine's sabotage, that she was forced to live on the run for over 500 years as he hunted her down.

**Katerina** is a member of the **Petrova Family**. She has ties to the **Salvatore Family**, **Gilbert Family**, **Mikaelson Family**.
