In 1653 Cromwell tired of everything around him and with lost of all hopes he decided to end the reign of the Rump Parliament. And so on 20 April at one of their sessions Cromwell said to all members that, Parliament was dismissed.
Cromwell agreed to be head of a powerful executive Council and for the remaining five years of his life he served as Lord Protector (he refused all efforts to make him King). His rule was a time of necessary social and religious laws on radical Protestant line. As a Lord Protector he also made an offensive alliance with France against Spain. He wanted to liberate Hispaniola from Spain, but this attempt was not successful (but he captured Jamaica). He also wanted to make a peace between Protestant Kings of Sweden and Denmark and he raised the prestige of Britain across the whole world.
Oliver Cromwell died on 3 September 1658 disillusioned and ill. He had been buried in Westminster Abbey with royal ceremony, but in 1661 he was exhumed and hanged in his shroud at Tyburn as a regicide. His head was cut off and put on public display for almost 20 years outside Westminster Hall.
