BAföG financial support for European students?
EU citizens can get Bafög but you have to fulfill some requirements that link you to Germany, for example:


have been living in Germany for over 5 years
your parents or spouse is working in Germany
you have been working in Germany before


You can find the full list here: In german though

If this is not applicable for you, you can try the DAAD (German Academic Exchange Program) which has an extensive selection of scholarships for students coming from or to Germany.
