He introduced the custom of producing poems for the new year and the monarch's birthday, which became one of the key duties of the position. After the appointment of William Wordsworth in 1843 the duties settled into an expectation, not requirement, for major court and national occasions. Alfred, Lord Tennyson held the post between November 1850 and October 1892.

Laureate Gower, John Kay, Andrew Bernard, John Skelton, Robert Whittington, Richard Edwards, Spenser and Samuel Daniel, as "volunteer Laureates." Sir William Davenant succeeded Jonson in 1638, and the title of poet laureate was conferred by letters patent on John Dryden in 1670 two years after Davenant's death, coupled with a pension of £300 and a butt of Canary Islands wine (also known as Sack (wine)). The post then became a regular institution, though the emoluments varied, Dryden's successors being T. Shadwell, who originated annual birthday and New Year odes; Nahum Tate; Nicholas Rowe; Laurence Eusden; Colley Cibber; William Whitehead; Thomas Warton;
