lets first focus on pre-Slavic waves of R1a
in my opinion first spread of R1a was Corded ware (circa 2900 BCE – circa 2350 BCE)...it went northwards and merged with I1 and I2a2 to give proto-germanic..southern part resulted in Urnfield and poshed border of R1a spread to south west and remained living there for 1000 years
that is why spread of R1a have same western borders as Urnfield culture (. 1300 BC – 750 BC)...
In my opinion Hallstat happens when R1b proto Celts get to rule over R1a Urnfield settlements...
this is why there is west (probably dominant R1b) and east hallstat (still dominant R1a)
we know that Jordanes says Slavi and Antes are biggest tribes remaining from once numerous Veneti race, implying Veneti is proto-Slavic and thus proto-Slavic was numerous race..so it rules out 6th century expansion from small area...
if the name Sloveni is old for part of proto-Slavic population and people..we could expect that name to be used already in east Hallstatt
godess Sulevia in east Hallstatt couild have been Slavia
and tribe Salluvi in southeast France could have been Slavi

presence of proto-Slavs in east Hallstatt gives possibility that slavic name for germanic people Nemci could have been derived from tribal name Nemetes that was also situated in east Hallstatt

note that east Hallstat is now mostly Slavic area...Two culturally distinct areas, an eastern and a western zone are generally recognised.[35] There are distinctions in burial rites, the types of grave goods, and in artistic style. In the western zone, members of the elite were buried with sword (HaC) or dagger (HaD), in the eastern zone with an axe.[24] The western zone has chariot burials. In the eastern zone, warriors are frequently buried with helmet and a plate armour breastplate.[23] Artistic subjects with a narrative component are only found in the east, in both pottery and metalwork.[36] In the east the settlements and cemeteries can be larger than in the west.[24]
The approximate division line between the two subcultures runs from north to south through central Bohemia and Lower Austria at about 14 to 15 degrees eastern longitude, and then traces the eastern and southern rim of the Alps to Eastern and Southern Tyrol.[citation needed]
Eastern Hallstatt zone
The eastern Hallstatt zone includes:
- eastern Austria: Lower Austria, Upper Styria
- eastern Czech Republic: Moravia
- southwestern Slovakia: Danubian Lowland
- western Hungary: Little Hungarian Plain
- eastern Slovenia: Hallstatt Archaeological Site in Vače (at the border between Lower Styria and Lower Carniola regions), Novo Mesto
- northern Croatia: Hrvatsko Zagorje, Istria
- northern and central Serbia
- parts of southwestern Poland

godess Sulevia in east Hallstatt couild have been Slavia
In ancient Celtic religion, Sulevia was a goddess worshipped in Gaul, Britain, and Galicia,[1] very often in the plural forms Suleviae or (dative) Sule(v)is. Dedications to Sulevia(e) are attested in about forty inscriptions, distributed quite widely in the Celtic world, but with particular concentrations in Noricum, among the Helvetii, along the Rhine, and also in Rome.
