This beautifully written book describes how owing to the passion of the Catholic James II, who attempted to abrogate the power of parliament to force Catholicism on an unwilling nation, Royalists and Roundheads alike united to deny him. He fled the country and a Convention summoned William and Mary from the Netherlands, Mary being James' daughter.
The parliament then summoned by William set limits then on the control the king could have over parliament which have remained to this day. This led to the establishment of Whig (Roundhead) and Tory (Cavalier) parties and gradually also the system of the monarch's ministers being selected by him or her from the dominant party.
The consequent stability also resulted in a more prosperous and militarily effective nation.
In Scotland it was a different story but the revolution led to an end to the attempt by Stuart kings to impose a strong episcopacy on a church which had strong lay traditions. Episcopacy was banned at the revolution.
In Ireland William imposed himself on the Catholics at the Battle of the Boyne, putting an end to James' last significant attempt to re-enter British politics.
Especially in England the 'Glorious Revolution' finally consolidated Elisabeth's achievement in establishing the Anglican Church by determining relations between Church, monarch and parliament after the trauma of extremes experienced in the earlier seventeenth century.
This is old school history with no references. Either you trust the historian or you don't. It's a great read.
