As an expert in historical studies, I would say that defining a "good era" is highly subjective and depends on various factors such as cultural, social, economic, and technological advancements, as well as individual perspectives on what constitutes a prosperous and peaceful time in history.

The Victorian era, which lasted from 1837 to 1901, was characterized by Queen Victoria's reign and included the Industrial Revolution, which brought about significant technological and economic changes.
