By the 10th century BC, archaeology records a slow development in agriculture from the entire area of Latium with the establishment of numerous villages. The Latins cultivated grains (spelt and barley), grapes (Vitis vinifera), olives, apples, and fig trees. The various "Latini populi" (lit. "Latin peoples") lived in a society led by influential clans ("gentes"). These clans were a sign of their tribal origin, which continued in Rome as the thirty "curiae" which organized Roman society. However, as a social unit the "gens" was replaced by the family which was headed by the "paterfamilias" - the oldest male who held supreme authority over the family.
