How can I write a 200-person guest list for Romeo and Juliet's hypothetical wedding? I'm allowed to use people from the book and people who were...

This is a fun assignment! You have a variety of ways you could go about this assignment, but I would suggest perhaps sticking with historical figures and fictional characters that existed in Verona, Italy, around the time of Romeo and Juliet. The exact time of Romeo and Juliet is unclear, but the time it was written is not. Romeo and Juliet was created by Shakespeare and performed between 1591 and 1595.

This is a fun assignment! You have a variety of ways you could go about this assignment, but I would suggest perhaps sticking with historical figures and fictional characters that existed in Verona, Italy, around the time of Romeo and Juliet. The exact time of Romeo and Juliet is unclear, but the time it was written is not. Romeo and Juliet was created by Shakespeare and performed between 1591 and 1595. Luckily, there was plenty happening in Verona during this period of the Renaissance. There was a significant population growth in Verona during this time due to successful ruling and peace. Many of the new buildings were created by the architect Michele Sanmicheli, and so studying this man and his relationships could be helpful for the wedding list. A link is provided below with a biography on Sanmicheli. 

Of course, it will be difficult to find 150 more names of historical people that were popular around the end of the 16th century in Verona without reviewing historical texts. As an alternative, you could potentially include characters from any play that was popular in Italy at the end of the 16th century. Commedia dell'arte was popular during this time, which is a different form than English drama because it routinely pulls from the same stock characters. These characters include the Zanni, Arlecchino, Bandello, Brighella, Il Capitano, Il Dottore, Pantalone, and the Columbine. 

Since many of these plays were not recorded, you could potentially make a leap and include characters on the wedding list who are from plays that were inspired by commedia dell'arte. These plays include The Tempest by William Shakespeare, Les Fourberies de Scapin by Moliere, and Servant of Two Masters by Carlo Goldoni. A quick search of these three plays would pull up a variety of characters that could likely be invited to the wedding.
