The number of MPs in Parliament grew steadily in the sixteenth century. There were 296 in 1500 and 400 in 1558. By 1600, there were 462.
In 1515, Parliament gained control over its members. They had to seek the approval of the Speaker if they wanted to leave before the end of the session.
In 1523, Thomas More, the Speaker, established the right of free speech for the first time. it was requested at the beginning of every Parliament subsequently.
In 1542, the Commons gained the right to enforce freedom from arrest. Hitherto, that had been enforced by the Crown.
Henry summoned four parliaments before 1529. The general atmosphere was not confrontational.
Parliament and King saw their relationship as cooperation. There were disagreements, but the main aim was to secure legislation for the king’s domestic policies.
Confrontation occurred in 1515 when MPs tried to limit the privileges of the Church. Some MPs were brought before Star Chamber and at least one died in the Tower as a result.
In 1523 there were arguments over demands for subsidies to pay for the costs of war.
Parliament met fewer times during the early reign of Henry VIII than during that of Henry VII and far less than in the fifteenth century.
From 1529, (the Reformation Parliament) Parliament became more important because Henry needed it to complete the break from Rome.
Parliament didn't gain any extra powers after the Reformation Parliament; it still met when the monarch summoned it and only then.
The Reformation Parliament was the exception and not the rule.
Tudor monarchs by and large lived on their traditional incomes and summoned Parliament when there was a particular need, e.g. 1529, 1558 and when extra resources were needed for war.
