Seat of power good for European crowd (6)

I believe the answer is:

throng

I'm a little stuck... Click here to teach me more about this clue!

'crowd' is the definition.
(I know that throng is a more specific form of the action crowd)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for throng that I've seen before include "Large gathering of people" , "A large crowd of people" , "Come in great numbers" , "A great crowd of people" , "Pack" .)

I've seen this clue in The Times.
