After the Great Sith War, House Mecetti sponsored the Sith-inspired Mecrosa Order, only to be defeated by the Jedi and House Pelagia during the Cleansing of the Nine Houses. During the last years of the Galactic Republic, CountDooku had close ties with the noble house. Despite their setbacks during the Cleansing, House Mecetti was still the most powerful family at the time of the New Order, and would have done anything to retain that power, even if it was harmful to the Tapani sector. During the New Order, Mecetti launched a purge of House Pelagia. However, fear of the Galactic Empire prevented them from attacking the other houses (particularly House Melantha, which was close with Imperial Center).
