Romeo and Juliet belongs to a tradition of tragic romances stretching back to antiquity. The plot is based on an Italian tale translated into verse as The Tragical History of Romeus and Juliet by Arthur Brooke in 1562 and retold in prose in Palace of Pleasure by William Painter in 1567.

Shakespeare may also have drawn on an earlier (hypothetical) Elizabethan play known today as the Ur-Hamlet, though some scholars believe he himself wrote the Ur-Hamlet, later revising it to create the version of Hamlet we now have.

The events of the tragedy are usually associated with the execution of Henry Garnet for complicity in the Gunpowder Plot of 1605.

Having squandered his estate, he needs 3,000 ducats to subsidise his expenditures as a suitor. Bassanio approaches his friend Antonio, a wealthy merchant of Venice who has previously and repeatedly bailed him out.
