Stuff:Legislature/date/explanation

The explanation template renders an explanation for the date of origin, namely:

This is the date of the Crown and Parliament Recognition Act, following on the Glorious Revolution (1688) and the Bill of Rights (1689). It serves as the default date of origin for institutions of modern democracy that have no more definite origin. Here we are speaking of institutions in the modern era, not antiquity or the middle ages; and institutions in large states, not city states.
