Bialya, with it's capital being the city of Bialya, and was ruled by petty dictator Rumaan Harjavarti. He tricked the extra-dimensional Champions of Angor into aiding him against the major world powers. He clashed with the Justice League International several times before being assassinated by the mysterious Queen Bee (not Zazzala) who took his place as ruler of Bialya.
Queen Bee brainwashed the Global Guardians to serve her. She was later killed by Rumaan's brother, Sumaan. He continued to use the Global Guardians until Dr. Mist broke their conditioning and they left Bialya.
Bialya was one of the first countries to fall victim to the rage of the criminal/superhero named Black Adam following the deaths of his wife, Isis, and brother-in-law, Osiris. As Black Adam slowly went mad he became unstable. Later on, in a talk between Atom Smasher and Black Adam, it was revealed that Death of the Four Horsemen was responsible for their deaths.
Bialya, ruled by Queen Bee is seen in the Young Justice episode Bereft. The Young Justice are in the desert of Bialya, where an extraterrestrial sphere has landed.
Batman battles Chemo off the coast of Bialya, but is poisoned by the radiation. Aquaman and The Atom journey into Batman's body to cure him just in time to stop Chemo's rampage and expose the Brain as the mastermind of the attack.
