The Libadarioi were a new family that first came to prominence in the Empire of Nicaea (1204–1261). They were considered one of the leading aristocratic families of the empire by George Pachymeres, and one of just five such new families. They held high civil and military office under the Palaiologoi. They may have been related to the Demetrios Libadas who held office (probably under the megas logariastes) in 1186. The first recorded Libadarios was a relative of the Mouzalon family. They were probably unrelated to the Limpidarios family that rose to prominence in the army and navy in the 14th century.

He remained loyal to the Palaiologoi during the rebellion of Alexios Philanthropenos. He bribed Alexios' mercenaries to betray him and then had him beheaded in December 1295.
