Today, haplogroup E-V13 has the highest density in the world in Albanian lands. The highest percentage is found in Kosovo, Malėsi, Labėri, Tirana/Durrės. Most of the main branches, such as: E-BY4459, E-Y146085, E-PH2180, etc., have begun to spread since the period of Albanian ethnogenesis, in late antiquity and the early Middle Ages.

At the branch level, there are quite large differences in the current distribution in Albanian lands. A large number of branches of E-V13 can be found in different regions, which suggests a presence in the Arbėr/Albanian population since the period of ethnogenesis. Among these are E-Y173822, E-Y146085, E-BY4459, E-PH2180, E-FT17132, E-Y159601, etc. The current diversity suggests that most of these lineages must have spread from the northeast about 1400-1800 years ago.
So basically the oldest clades which have the highest in group diversity entered Albanians sometime in Late Antiquity or earlier possibly , they follow the same pattern as J-L283 clades and R1b such as R-Z2705, J-PH4679, R-Z29758. Lineages such as J-PH4679 and R-Z29758 have branches that go back 3000-4000 years, have in group diversity and represent the linguistic ancestor and oldest layer of Albanian. Even the oldest E-V13 clades entered way later and followed them way later.
