Final answer:
Bars and theaters were allowed in Southwark but not in London due to different jurisdiction and regulations. Southwark was outside the jurisdiction of London's city officials and less restricted, allowing for more freedom for entertainment establishments.
Step-by-step explanation:
The reason why bars and theaters were permitted in Southwark, but not in London, is primarily because of the different jurisdiction and regulations between the two areas. Theatrical activities were illegal within the city limits of London due to the strict regulations governed by city officials who were concerned with moral and public order. This was not the case in Southwark, which was outside the jurisdiction of London's city officials and thus allowed more freedom for such establishments.
Furthermore, acting troupes in Elizabethan England required patrons for protection and were subject to approval and licensing by authorities such as the Master of the Revels. While some activities, like public theaters, were restricted within London, they thrived in Southwark, showing the significant influence of regulation on cultural activities. This divide allowed Southwark to become a hub for entertainment, drawing audiences across the Thames for performances.
