House of Commons and Political History

'Common' can mean 'shared', but also 'ignoble'.  Now, the most politically significant application of the latter might be the U. K. House of Commons, which is distinguished from the House of Lords, as well as from a Royal Family.  So, it is perhaps ironic that the ignoble part of the government is also the most powerful.  But, it is also instructive, insofar as that Parliament embodies the history of Politics over the past millennium, with a Monarch, Theological Lords, and landed Lords, having yielded all but ceremonial rule to a Democracy of Commoners.
