Richard III (play) "Hamlet" is shorter than its Quarto counterpart. The play is often abridged; for example, certain peripheral characters are removed entirely. In such instances, extra lines are often invented or added from elsewhere in the sequence to establish the nature of characters' relationships. A further reason for abridgment is that Shakespeare assumed that his audiences would be familiar with his "Henry VI" plays and frequently made indirect references to events in them, such as Richard's murder of Henry VI or the defeat of Henry's wife, Margaret.

Shakespeare in performance of the century Shakespeare's plays had been established as part of the repertory outside of Great Britain: not only in the United States but in many European countries. In the 18th century, Shakespeare dominated the London stage, while Shakespeare productions turned increasingly into the creation of star turns for star actors. After the Licensing Act of 1737, one fourth of the plays performed were by Shakespeare, and on at least two occasions rival London playhouses staged the very same Shakespeare play at the same time ("Romeo and Juliet" in 1755 and "King Lear" the next year) and still commanded audiences.
