Nepotism has been a reality throughout history, even in understandable forms like royal lineage, but the term as used today is often meant in a derogatory sense. In that spirit, who in history received the best inheritance undeservedly and did the least or worst with it?

This question has been removed because it violates the rule on poll-type questions. These poll-type questions do not lend themselves to answers with a firm foundation in sources and research, and the resulting threads usually turn into monsters with enormous speculation and little focussed discussion. “Most”, “least”, "best" and "worst" questions usually lead to vague, subjective, and speculative answers. If you'd like, you may PM /u/caffarelli to have your question considered for an upcoming Tuesday Trivia thread.
