When discussing historical events, it's common to use the phrase "in the time of" to indicate the era being referred to. However, there are several synonyms for this phrase that can add variety and sophistication to your writing. For instance, you might use "during the reign of" to describe a specific monarch's rule, or "in the age of" to capture the feeling of a particular time period. Similarly, "amidst" or "in the midst of" can convey a sense of events unfolding in the middle of a larger historical shift. Other options might include "when" or "while" -- both of which allow you to be more specific about the duration or timing of events.
