Sakura Kingdom

The Sakura Kingdom (サクラ王国 Sakura Oukoku, lit. "Cherry Blossom Kingdom"), formerly the Drum Kingdom (ドラム王国 Doramu Oukoku), is a kingdom located on Drum Island.This is where Strawhat Pirates Chopper come from

When Sakura Kingdom was Drum Kingdom, it was ruled by the royal family of Drum Island. It once had a kind ruler, and many of the greatest doctors on the Grand Line. But when the king died, and his son, Wapol came into power, things took a turn for the worse. Wapol issued that the 20 best doctors work exclusively for him (the Isshi-20), while the rest of the doctors were banished or killed.

Then, the Blackbeard Pirates came and invaded the island, and Wapol fled in fear. Since then, Drum Island was left without a ruling government, and Dr. Kureha took residence in his castle. When Wapol came back to try to retake his kingdom, it was also the same time when the Straw Hat Pirates landed on the island, looking for a doctor to help a sick Nami. Wapol then tried to destroy Dr. Hiruluk's flag which was standing on top of Drum Castle. In response to this, Luffy used Gomu Gomu no Bazooka to knock Wapol away from the kingdom.

After Wapol was blown away by Luffy, the people of the kingdom decided to make Dalton the king, who decided to erase the bitter effect of Wapol's actions by renaming the kingdom "Sakura" in memory of Dr. Hiruluk and his goal of using the Sakura to cure all diseases of the heart. The new kingdom also used Dr. Hiruluk's Jolly Roger as the flag. Since raising the Jolly Roger is considered a huge crime, it's possible that the Sakura Kingdom is no longer a member of the World Government, or the Counsel of Kings.
