The first performance of Romeo and Juliet took place in the autumn/winter of 1594, when the playhouses reopened for the first time after a sustained outbreak of the plague had forced the authorities to close all the playhouses in London in January 1593. During this period, over 10,000 people in London alone died from the disease, and Shakespeare emphasizes the relevance of the plague for his audience by using it in Romeo and Juliet to prevent Friar Laurence's message from reaching Romeo in Mantua.
