History Of One Piece ! :)

The series begins with the execution of Gol D. Roger, a man known as the King of the Pirates. He told the legend of his treasure, the One Piece, just before he was executed. Roger's death caused a Great Pirate Era (大海賊時代, Dai Kaizoku Jidai^?) as countless pirates set out to look for his treasure.
Twenty years have passed since Roger's execution, and Monkey D. Luffy, a young boy inspired by the pirate known as "Red-Haired" Shanks, sets off on a journey from the East Blue to succeed Roger and find the treasure. Along the way, he organizes and leads a crew named the Straw Hat Pirates. The crew consists of swordsman Roronoa Zoro, the navigator and thief Nami, the liar and cowardly sharpshooter Usopp, the womanizing chef Sanji, the doctor and anthropomorphized deer Tony Tony Chopper, the archaeologist and former enemy Nico Robin, the cybernetic shipwright Franky, and the musician skeleton Brook.
The crew crosses paths with diverse villains, such as Buggy the Clown, Seven Warlords of the Sea, the Marines, who place bounties on Luffy and Zoro's heads, and Arlong, a fishman and member of the former Sun Pirates. They encounter Baroque Works, the crime syndicate responsible for a civil war in the desert kingdom of Alabasta, and meets Blackbeard, whose dream is also to become the King of the Pirates. The crew also encounters Eneru, the ruler of the floating island Skypiea. Later, the crew meets the Marine admiral Aokiji, who reveals that Robin was involved in searching for Poneglyphs, stones with markings left by an ancient civilization whom Roger himself was also able to read. The crew also encounters Cipher Pol No. 9, the intelligence agency responsible for the destruction of Robin's homeland, whose actions cause them to declare war on the World Government. After an epic battle at Enies Lobby, the crew defeats CP9, avenging the lives of people lost in the destruction, and each member receives bounties on their heads.
When the crew finishes the first half of their journey and prepare to sail off to the New World, the second half of the Grand Line, the crew gets separated during a battle at the Sabaody Archipelago. During this time, the Marines sentence Luffy's older brother and Roger's son Portgas D. Ace to be executed, and they hold a war against a group of pirates led by Whitebeard. Luffy eventually rescues Ace, but both Whitebeard and Ace are killed in the ensuing chaos. Later, Luffy and the crew undergo rigorous training regimens, some under the tutelage of prominent figures. Two years later, the crew regroups and resume their journey to the New World, traveling first to Fishman Island. However, the crew is drawn into a coup d'etat staged by a group of fishmen pirates.
