Exclusion Crisis

The Exclusion Crisis ran from 1679 until 1681 in the reign of King Charles II of England, Scotland and Ireland. Three Exclusion bills sought to exclude the King's brother and heir presumptive, James, Duke of York, from the thrones of England, Scotland and Ireland because he was Roman Catholic. None became law. Two new parties formed. The Tories were opposed to this exclusion while the "Country Party", who were soon to be called the Whigs, supported it. While the matter of James's exclusion was not decided in Parliament during Charles's reign, it would come to a head only three years after he took the throne, when he was deposed in the Glorious Revolution of 1688. Finally, the Act of Settlement 1701 decided definitively that Catholics were to be excluded from the English, Scottish and Irish thrones, now the British throne.

16 May 1877 crisis

When the royalist president Patrice MacMahon dismissed the Opportunist Republican prime minister Jules Simon, the parliament on 16 May 1877 refused to support the new government and was dissolved by the president. New elections resulted in the royalists increasing their seat totals, but nonetheless resulted in a majority for the Republicans. Thus, the interpretation of the 1875 Constitution as a parliamentary system prevailed over a presidential system. The crisis ultimately sealed the defeat of the royalist movement, and was instrumental in creating the conditions of the longevity of the Third Republic.

The war also featured a series of massacres of Jews by de Montfort's supporters including his sons Henry and Simon, in attacks aimed at seizing and destroying evidence of baronial debts. To bolster the initial success of his baronial regime, de Montfort sought to broaden the social foundations of parliament by extending the franchise to the commons for the first time.
