One Piece,Gol D. Roger

Gol D. Roger, known to most as Gold Roger, was a legendary pirate who was known as the Pirate King, captain of the Roger Pirates, and owner of the legendary treasure known as "One Piece". He was also the lover of Portgas D. Rouge and biological father of Portgas D. Ace.
Roger was famed as the man who did what no one thought possible - conquering the Grand Line and amassed a vast fortune, but he knew that he would soon die from an incurable disease. He disbanded his crew before turning himself in to be executed. The World Government intended to have Roger be publicly executed to discourage piracy, but his last words had the opposite impact. He stated that anyone who can find his treasure can claim it.
As such, this made Roger single-handedly responsible for starting the Golden Age of Pirates.
