Eleven were jailed for rape and the 12th man was jailed for sexual activity with a child under 16 by Bradford Crown Court.
Their white British victim from the West Yorkshire town of Keighley in northern England was aged 13 and 14 when she was repeatedly raped and passed around between the men, the court heard during the trial.
The men were led by ringleader and drug dealer Ahmed Al-Choudhury, who facilitated most of the offences but then fled abroad to Bangladesh.
"Exactly the same attitude to the 13/14 year old girl who you all sexually abused and exploited for your own selfish gratification. None of these defendants had any concern for the victim. They were totally uninterested in her welfare and what damage they were causing her."

In a statement, she said: "My perception of what a normal relationship is, is warped. Trust issues effect every aspect of my life. I have also had many physical effects. I was physically assaulted and punched and kicked and these hurt when I am tired.
"My moods are very variable and can be up and down at any time. I have no coping mechanisms and feel out of control. The court process has been very difficult.
