A chain of islands on africas west coast being incoperated into Rome.

Four Gallia class cruisers are sent to finalize things, the population on the islands is unarmed, and without military, they will be peacefully occupied unless resistance is to start, however this is unlikely.
They're called Cape Verde
EDIT: I think that Cape Verde might be further south, those are probably Canary Islands
Several thousand nationalists begin demanding the withdrawal of Roman Forces. Chanting loudly in Spanish in front of government buildings.
Also they speak english there
