In 1480 the Maravi Empire was founded by the kalonga (paramount chief of the Maravi) from the Phiri clan, one of the main clans, with the others being Banda, Mwale and Nkhoma. The Maravi Empire stretched from the Indian Ocean through what today is Mozambique to Zambia and large parts of Malawi. The political organization of the Maravi resembled that of the Luba and is believed to have originated from there. The primary export of the Maravi was ivory, which was transported to Swahili brokers.
