I would say more than 1500 people forcibly relocated to the Island in the first place to work in the plantation and stayed there for hardly a century.

While there are plenty of arguments on what actually defines a nation from both historic cultural perspectives this one is a far stretch for any acceptable "litmus" test for a nation, even if it's simple because they never had the political legitimacy to being a nation state, not to mention ever had the capabilities of forming one.

Where they've mistreated? yes, do they deserve a compensation? yes, are they a nation? well not really if we are frank about it.
