Which region was the last to become part of the UK? *

answer; i believe the above statement is (true);

the romans were initially interested in expansion via sicily (which at that time was a cultural melting pot), part of which lay under carthaginian control. at the start of the first punic war (264-241 bc), carthage was the dominant power of the western mediterranean, with an extensive maritime empire

because they can and they wanted to.
