William Lynn, 45, had previously pled guilty at the High Court at Glasgow to four charges involving the repeated rape and violent assault of four different victims.
All the incidents involved aggravations of assault to severe injury, one also to the danger of life and one charge of assault to severe injury, permanent disfigurement and danger of life.
The offences took place between 1998 and 2008.
Sineidin Corrins, Deputy Divisional Procurator Fiscal and Head of the Glasgow Area Sexual Offences Unit, said: “William Lynn is guilty of a horrifying catalogue of domestic abuse and rape, occurring over two decades against four different partners.
“His conviction and sentence today is the culmination of a complex investigation involving the specialist team of prosecutors in the Glasgow Area Sexual Offences Team and National Sexual Crimes Unit, and Strathclyde Police’s Domestic Abuse Task Force.
“The crimes have had a significant affect on the lives of his victims, who were kept fully advised of developments in the case from the outset by dedicated professionals both within the Police and in COPFS’ Sexual Offences and Victim Information and Advice Teams, and who were spared the need to give evidence in court through the securing of this plea.
“I hope their bravery in seeking justice encourages any others who may be the victims of such abuse to come forward. Whether or not the crime happened some time ago, whether or not it happened behind closed doors – our specialists stand ready to investigate and bring domestic abusers and sexual offenders to justice.”
