IT was also Harry's ancestors who ended British participation in the transatlantic slave trade . "Are we not men and brother too" was the rally cry. Starting in 1779 Britain worked to end slavery and by 1832,  50 years, it was all over, but no thanks for that.  The Arabian slave trade  was in full operation across Africa a 1000 years prior to Europeans,  and continues today  Virtually every Islamic country continues some form of slavery.  But blame Harry's lineage that it happened at all, before and after they were involved.

As soon as Britain ended its participation in slavery  they got richer than ever with the Industrial Revolution. Not a single black man was ever again in British  slave chains, yet you are not pleased by that.
