<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">powerful family</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for dynasty that I've seen before include "show" , "Ruling sequence" , "Sequence of hereditary rulers" , "TV series" , "Sequence of powerful leaders in the same family" .)
