Henry Tudor and other exiles defeated and killed Richard III on Bosworth field, which ends the War of the Roses. As King, Henry VII restored order to the nation. He was readily accepted as King because he was descended from both royal lines who were fighting each other and married a woman who also was in the royal bloodline. Henry was intelligent and sensitive. He weighed alternatives and possible consequences before taking action. He was convinced by reason on what plans to make. His primary strategy was enacting and enforcing statutes to shore up the undermined legal system, which includes the establishment of a new court: the Court of the Star Chamber, to obtain punishment of persons whom juries were afraid to convict. It had no jury. The Star Chamber was the room in which the King's council had met since the 1300s. In his reign of 24 years, Henry applied himself diligently to the details of the work of government to make it work well. He strengthened the monarchy, shored up the legal system to work again, and provided a peace in the land in which can later flourish a renaissance of the arts and sciences, culture, and the intellectual life. The most prevalent problems were: murder, robbery, rape or forced marriage of wealthy women, counterfeiting of coin, extortion, misdemeanors by sheriffs and escheators, bribing of sheriffs and jurors, perjury, livery and maintenance agreements, idleness, unlawful plays, and riots. Interference with the course of justice was not committed only by lords on behalf of their retainers; men of humbler station were equally prone to help their friends in court or to give assistance in return for payment. Rural juries were intimidated by the old baronage and their armed retinues. Juries in municipal courts were subverted by gangs of townsmen. Justices of the Peace didn't enforce the laws. The agricultural work of the nation had been adversely affected.
