I vassalized Portugal. Ten years after, I can annex it. I must choose to wait or not for Portugal to make some colonies before to annex it. In case I will gain its dependencies later, I will wait. Else I would annex it now.
Is the annexation of a vassal giving you the control of its colonial nations? Do you gain all its dependencies?
Best Answer
Yes, you will gain all colonies.
They will however keep their name and color IIRC.
