Duleep Singh was kidnapped by Britishers, tortured and forcibly conmverted the Christianity. Then the Sikh army was used by the British to capture Bihar and Bengal. After a few years, British used Bihari Msulims ( which refer to as Purvaiyas ) to subjugate Sikhs.
Britishers ruled India for 100 more years by making Indians fight each other.
Manmohan Singh is another Duleep Singh. He should be removed from PM as soon as possible. I am surprised many Indians have forgotten the period of slavery.
