The paper examines, through the richness of salt in Transylvania, the causes that led to the migrations from Anatolia to the southern Balkans and then to central Europe, especially in Transylvania. Among the factors that led to these migrations were firstly climate changes: warming in Holocene, favourable climate in Transylvania around 6000 BC, the salt riches here that provide salt for several millennia. The Holocene warming has led to desertification (the disappearance of forests in the lowlands of Anatolia), the settlements have a shorter timespan, and most of them have only one habitation level (after 6000 BC). These have led to migrations towards the Aegean Sea (Kirokitia) and through the islands or the coasts of Thrace to mainland Greece and from there through the Balkans to the Carpathian Zone, where important salt deposits can be found. Successive migrations have also determined a great cultural unity, observable especially in the evolution of ceramics in the Early Neolithic in the Balkans and southern Central Europe, situations analysed and presented with similar developments from those areas.
