Should I end a sentence with prepositions? ?

Question

Are these the same?

1)Their ancestors were the franks, Germanics tribes to which Clovis and Charlemagne belonged.

2) Their ancestors were the franks, Germanics tribes which/that Clovis and Charlemagne belonged to.

What's the difference?

Answer 1

Both are correct:depending on "which" .

Example:

This is the city in which I live.

This is the city which I live in.

It depends if you already use the preposition with "which",you can't end it with that preposition.But if you don't,then you can.

Answer 2

The first one is right.  The second one isn't because you ended it with a preposition.
