A couple murdered 17-year-old Shafilea Ahmed at their Warrington home because they believed her conduct was bringing shame on the family, a court heard.
As her parents went on trial for murder, the prosecution told Chester Crown Court they had killed her because she refused to obey them.
Opening the case against the Ahmeds, Mr Edis told the jury: "The defendants, having spent the best part of 12 months trying to really crush her, realised they were never going to be able to succeed and finally killed her because her conduct dishonoured the family, bringing shame on them."
Shafilea Ahmed's sister Alesha has claimed she saw her parents murder the 17-year-old during their trial at Chester Crown Court.
Alesha's evidence is described in court as the "final piece of the puzzle which police have been trying to solve for many years.
The court were told that before Shafilea Ahmed's death, she was taken to Pakistan for a hastily arranged marriage. When she was there she drank bleach.
The prosecution say this was an "act of desperation". She later returned to the UK.
Her parents Iftikhar and Farzana Ahmed deny murdering Shafilea at their home in Warrington in September 2003.
