The bank issued its first banknotes in 1694, although before 1745 they were written for irregular amounts, rather than predefined multiples of a pound. It tended to be times of war, which put inflationary pressure on the British economy, that led to greater note issue. In 1759, during the Seven Years' War, when the lowest-value note issued by the Bank was £20, a £10 note was issued for the first time. In 1793, during the war with revolutionary France, the Bank issued the first £5 note. Four years later, £1 and £2 notes appeared, although not on a permanent basis. Notes did not become entirely machine-printed and payable to the bearer until 1855.
