By the 15th century, two confederations, "hanau", of social groupings, "mata", existed, based on lineage. The western and northern portion of the island belonged to the Tu'u, which included the royal Miru, with the royal center at Anakena, though Tahai and Te Peu served as earlier capitals. The eastern portion of the island belonged to the 'Otu 'Itu. Shortly after the Dutch visit, from 1724 until 1750, the 'Otu 'Itu fought the Tu'u for control of the island. This fighting continued until the 1860s. Famine followed the burning of huts and the destruction of fields. Social control vanished as the ordered way of life gave way to lawlessness and predatory bands as the warrior class took over. Homelessness prevailed, with many living underground. After the Spanish visit, from 1770 onwards, a period of statue toppling, "huri mo'ai", commenced. This was an attempt by competing groups to destroy the socio-spiritual power, or "mana", represented by statues, making sure to break them in the fall to ensure they were dead and without power. None were left standing by the time of the arrival of the French missionaries in the 1860s.
