For defense of the nation, especially the safeguard of the seas, Parliament allotted the king for life, 3s. for every tun of wine imported and an additional 3s. for every tun of sweet wine imported. From about 1413, tunnage on wine and poundage on merchandise were duties on goods of merchants which were regularly granted by Parliament to the king for life for upkeep of the Navy. Before this time, such duties had been sporadic and temporary.
The most common ailments were eye problems, aching teeth, festering ears, joint swelling and sudden paralysis of the bowels. Epidemics broke out occasionally in the towns in the summers. The plague swept London in 1467 and the nation in 1407, 1445, and 1471. Leprosy disappeared.
Infirmaries were supported by a tax of the king levied on nearby counties. The walls, ditches, gutters, sewers, and bridges on waterways and the coast were kept in repair by laborers hired by commissions appointed by the Chancellor. Those who benefited from these waterways were taxed for the repairs in proportion to their use thereof.
Alabaster was sculptured into tombs surmounted with a recumbent effigy of the deceased, and effigies of mourners on the sides. Few townsmen choose to face death alone and planned memorial masses to be sung to lift his soul beyond Purgatory. Chantries were built by wealthy men for this purpose.
Chemical experimentation was still thought to be akin to sorcery, so was forbidden by King Henry IV in 1404.
Gold was minted into coins: noble, half noble, and farthing.
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 kings' 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 of the barons in Parliament were forbidden to bear arms, so they appeared with clubs on their shoulders. When the clubs were forbidden, they came with stones concealed in their clothing.
Kings created dukes and marquesses to be peers. A duke was given creation money or allowance of 40 pounds a year. A marquess was given 35 pounds. These new positions could not descend to an heiress, unlike a barony or earldom. An earl was given 20 pounds, which probably took the place of his one-third from the county. King Henry VI gave the title of viscount to several people; it had an allowance of 13.3 pounds and was above baron. It allowed them to be peers. There were about 55 peers. In King Edward IV's reign, the king's retinue had about 16 knights, 160 squires, 240 yeomen, clerks, grooms, and stablemen. The suitable annual expense of the household of the king was 13,000 pounds for his retinue of about 516 people, a duke 4,000 pounds for about 230 people, a marquess 3,000 pounds for about 224 people, an earl 2,000 pounds for about 130 people, a viscount 1,000 pounds for about 84 people, a baron 500 pounds for about 26 people, a banneret Barons' households also included steward, chaplains, treasurer, accountants, chamberlain, carvers, servers, cupbearers, pages, and even chancellor. They were given wages and clothing allowances and had meals in the hall at tables according to their degree. The authority of the King's privy seal had become a great office of state which transmitted the King's wishes to the Chancery and Exchequer, rather than the King's personal instrument for sealing documents. Now the king used a signet kept by his secretary as his personal seal. Edward IV made the household office of secretary, who had custody the king's signet seal, a public office. The secretary was generally a member of the council. Edward IV invented the benevolence, a gift wrung from wealthy subjects.
