Charles Oman,
A History of England
“ Thus died Earl Simon the Righteous, a man much loved by those who knew him well, courteous and kindly, pious and honest, wise and liberal. But it cannot be denied that he was touched by an overweening ambition, and that when England fell beneath his hand, he ruled her more as a king than a regent, and forgot that he was but the deputy and representative of the nation. His rise and success freed England from the thriftless rule of Henry, and set a boundary to the use of the royal prerogative. His short tenure of power gave the realm the valuable gift of the full and representative Parliament. ”
