in English literary history, conflict involving the Elizabethan playwrights Ben Jonson (Jonson, Ben), John Marston (Marston, John), and Thomas Dekker (Dekker, Thomas). It covered a period when Jonson was writing for one children's company of players and Marston for another, rival group.

In 1599 Marston presented a mildly satirical portrait of Jonson in his Histrio-mastix. That same year Jonson replied in Every Man Out of His Humour, ridiculing Marston's style as “fustian.” Some scholars have thought that the character of Brabant Senior in Marston's Jack Drum's Entertainment (1599) was a lampoon on Jonson, though this is disputed. Marston certainly thought himself attacked in Jonson's Cynthia's Revels (c. 1600), and he satirized Jonson as Lampatho Doria in What You Will (1601). Meanwhile, in Poetaster (1601) Jonson represented Marston as an inferior poet and a plagiarist; he also extended the attack to Dekker, satirized as a hack playwright. Dekker replied with Satiro-mastix (1601), which lampooned Jonson as “the humorous poet.” The quarrel had been patched up by 1604, when Marston dedicated The Malcontent to Jonson.

Some scholars have seen the quarrel as based on a difference of opinion about the nature of drama; it was certainly sharpened by the intense competition that existed between children's companies at the time, which were so popular that in Hamlet Shakespeare refers to the fact that adult actors were forced to undertake provincial tours because of the boys' popularity.
