Almerac is a planet populated by Almeracians, a technologically advanced warrior society that was enthralled with the cycle of constant military activity. They lived under imperial rule by the House of the Blood Royale, a product of generations of selective breeding.
When Queen Maxima witnessed Superman fighting in gladiatorial combat on Warworld. Faced with the dilemma of her own generation's disappointing crop of prospective mates, Maxima sent out a near-perfect duplicate of herself to investigate the Kryptonian on Earth. Her servant, Sazu, did not approve of Superman and destroyed Maxima's duplicate. Sazu's actions, however, only seemed to strengthen her resolve. 
When Maxima arrived on Earth, she was shocked by his rejection, but stayed hoping in make Superman her mate, but in her absence the planet fell to invaders. The first attack occurred when Brainiac seized control of Warworld and nearly destroyed the planet. After a brief respite, Starbreaker began ripping Almerac apart, shifting it out of its orbit and feeding off the planet's death throes. The once proud civilization of the Almeracians barely had time to recover from the tragedy before the arrival of Imperiex sealed the planet's doom.
