I have not mentioned on two particular groups I feel deserve some note:
I don't have much information on them, and any help would be great!
The Romanians and the Roma.
The Romanians are the largest cultural population in Transylvania. They have a wonderful culture and values. They have for the most part lived there for many centuries, though the general view in the West is that Transylvania was not populated until the 1960's. The Romanian population was always there.
During the Hungarian rule there was a strong push to destroy this unique culture. After the unification with Romania, the role was reversed, and people were encouraged to celebrate their culture.
As for the Roma, there is not much to be said in the West (by the West I mean North America) much of what does come out is not helpful in understanding their culture and heritage. I wish that there was some books that show them in a light that allows people to see them as a valuable part to Romania.
My search about Transylvania continues...
