Input: Article: In the later Imperial era, the burial and commemorative practises of Christian and non-Christians overlapped. Tombs were shared by Christian and non-Christian family members, and the traditional funeral rites and feast of novemdialis found a part-match in the Christian Constitutio Apostolica. The customary offers of wine and food to the dead continued; St Augustine (following St Ambrose) feared that this invited the "drunken" practices of Parentalia but commended funeral feasts as a Christian opportunity to give alms of food to the poor. Christians attended Parentalia and its accompanying Feralia and Caristia in sufficient numbers for the Council of Tours to forbid them in AD 567. Other funerary and commemorative practices were very different. Traditional Roman practice spurned the corpse as a ritual pollution; inscriptions noted the day of birth and duration of life. The Christian Church fostered the veneration of saintly relics, and inscriptions marked the day of death as a transition to "new life".

Now answer this question: When was Christian attendance at Parentalia become forbidden by the Christians?

Output: AD 567

Input: Article: Control of labour and inter-group conflict is characteristic of corporate-level or 'tribal' groups, headed by a charismatic individual; whether a 'big man' or a proto-chief, functioning as a lineage-group head. Whether a non-hierarchical system of organization existed is debatable, and there is no evidence that explicitly suggests that Neolithic societies functioned under any dominating class or individual, as was the case in the chiefdoms of the European Early Bronze Age. Theories to explain the apparent implied egalitarianism of Neolithic (and Paleolithic) societies have arisen, notably the Marxist concept of primitive communism.

Now answer this question: What type of disagreement existed in tribal groups that were controlled by charismatic leaders?

Output: inter-group conflict
