Seized part of Dublin and showed no respect (4,9)

'dublin and showed no respect' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'seized part' is the wordplay.
I cannot really see how this works, but
'seized' could be 'took' (I've seen this before) and 'took' is present in the answer.
'part' could be 'ti' (ti is a kind of part) and 'ti' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'of' acts as a link.

Can you help me to learn more?
