The national anthem of South Sudan, "South Sudan Oyee!", was officially adopted on July 9, 2011—the very day the country declared independence from Sudan. The lyrics were penned by Juma Joseph Beda, and the music was composed by Samuel Mbuoti Madut. The anthem celebrates the nation's hard-won freedom, its diverse peoples, and the land's natural beauty. "Oyee" is a traditional exclamation of joy and victory, making the title a rallying cry for the world's youngest nation.
