Thomas Wentworth, Earl of Strafford, Charles I's chief minister, was executed on Tower Hill in London on May 12, 1641, following impeachment by the Long Parliament for alleged treason. His death removed a key supporter of royal authority and signaled Parliament's determination to hold the king's advisors accountable.

Strafford's execution inspired elegiac poetry from Royalist writers who portrayed him as a martyr to parliamentary vengeance, while Parliamentary supporters celebrated it as justice. The event deepened the emotional polarization reflected in Civil War poetry, with competing narratives of tyranny and liberation shaping how poets framed the conflict's moral dimensions.
