I believe the answer is:
apartheid
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">segregation</span>' is the definition.<br/ ><span class="explanation-format__explanation">(apartheid is a kind of segregation)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for apartheid that I've seen before include "Tyrannical system in S Africa now abandoned" , "System of segregation formerly practised in South Africa" , "Network of bars no longer" , "divisive policy" , "Former South African political system" .)
