It`s not true.
Albanians are descendants of the Illyrians, while Romanians are descendants of the Dacians. These two ancient peoples, who continue today to live in the same territory as in ancient times, were once neighboring to each other. Remember, South Slavs had not yet reached the Balkans.They were still in Asia or God know where.
This explain why some romanian words(70 in a total of 160 words that can not be explained with latin, slav, german, hungarian or turkish) can be explained with the help of Albanian language.
We know the contribution of Albanians in the creation of the Greek and Serb modern nations. This happened due to the assimilation of Albanian element, etc. But we can not say that Romanians are simply another Albanian diaspora as are trying to argue Hungarian nationalists. It's not true.
We are two different nations. Once neighbouring, but always different.
Confusion is because terms Dacians and Free Dacians.
Free Dacians were not ethnic Dacians.
Free Dacians, Carpi, and probably Costoboci, and maybe another tribe were Albanians, probably Carpi were Gheg Albanians.
Some tribes around Dacia were Sarmatian, German, Baltic or Slavic etc.
In Hungarian sources someone can find that Romanians and Albanians lived together in today's Albania, but no, Romanians and Albanians (Dacians and Free Dacians) lived in Romania and beyond, for example Carpi (Free Dacian tribe) lived in Carpatian mountains today's it is mostly in province Moldova in Romania.
