Our paper (poster) presents some archaeological finds from North-western Romania (county Satu Mare) which indicate cultural interferences and changing population. We have to remark, first of all, that there is a great difference in the research of the 1st-5th centuries between the northern part of the zone in question (the valley of Somes river) and the southern one (the valley of Crasna and Ier). In the Somes valley there were many systematic arhchaeological works made unsimilarly to the valley of Crasna and Ier rivers, where only some test excavations and stray finds were made.

In the 1st-5th centuries, the first change of the population which is reflected in the archaological finds, is the penetration of the Przeworsk culture into the valley of Someș and Crasna rivers in the middle of the 2nd century. This is illustrated by occasional finds such as the warrior burials from Apa, Boienești, Cehăluț and the systematic excavations, as the large cemetery from Medieșu Aurit. In the latter site the excavation has been carried out since the 1960s, but the results are still unpublished. Some recent researches made in the 1990s identified a number of settlements with Przeworsk elements such as Petea, Lazuri, Supur. It is very interesting that the Przeworsk finds are found in the same context as the elements of Dacian material culture, making a mixed Dacian-Germanic cultural horizon, which later will be greatly influenced by the Roman material culture.
 New elements in the archaeological discoveries of North-West Romania are appearing in the 4th century, such as the Sîntana de Mureș – Cherniahov pottery ware, settlement of Lazuri and the isolated burials from Dindești.
 The finds from the 5th century are concetrated in the valley of Ier. There are some isolated burials from Ghenci, Dindești, Andrid with many grave-goods that have good analogies in the Carpathian basin and the Middle Danubian region.
