King Henry IV lost power to the Commons and the Lords because he needed revenue from taxes and as a usurper King, he did not carry the natural authority of a King. The Commons acquired the right to elect its own speaker. The lords who helped the usurpation felt they should share the natural power of the kingship. The council became the instrument of the Lords. Also, the Commons gained power compared to the nobility because many nobles had died in war. The consent of the Commons to legislation became so usual that the justices declared that it was necessary. The Commons began to see itself as representative of the entire commons of the realm instead of just their own counties. Its members had the freedom to consider and debate every matter of public interest, foreign or domestic, except for church matters. The Commons, the poorest of the three estates, established an exclusive right to originate all money grants to the king in 1407. The Speaker of the Commons announced its money grant to the king only on the last day of the parliamentary session, after the answers to its petitions had been declared, and after the Lords had agreed to the money grant. It tied its grants by rule rather than just practice to certain appropriations. For instance, tunnage and poundage were appropriated for naval defenses. Wool customs went to the maintenance of Calais, a port on the continent, and defense of the nation. It also put the petitions in statutory form, called "bills", to be enacted after consideration and amendment by all without alteration. Each house had a right to deliberate in privacy. In the Commons, members spoke in the order in which they stood up bareheaded. Any member of Parliament or either house or the king could initiate a bill. Both houses had the power to amend or reject a bill. There were conferences between select committees of both houses to settle their differences. The Commons required the appointment of auditors to audit the King's accounts to ensure past grants had been spent according to their purpose. It forced the King's council appointees to be approved by Parliament and to be paid salaries. About 1430, kings' councilors were required to take an oath not to accept gifts of land, not to maintain private suits, not to reveal secrets, and not to neglect the king's business. A quorum was fixed and rules made for removal from the council. For the next fifty years, the council was responsible both to the king and to Parliament. This was the first encroachment on the King's right to summon, prorogue, or dismiss a Parliament at his pleasure, determine an agenda of Parliament, veto or amend its bills, exercise his discretion as to which lords he summoned to Parliament, and create new peers by letters patent [official public letters]. Parliament was affected by the factionalism of the times. The speaker of the commons was often an officer of some great lord. In 1426, the retainers
