To identify natural segments, I should examine the actual distribution of key dimensions. The 'Recognition' column (temporal, ~118 distinct values) and 'Additional_recognition' column (~16 distinct) look promising for grouping. I'll query to see the distinct values and their frequencies for these potential grouping dimensions, along with examining the temporal spread of Begin_reign to understand if there are natural era breaks.",
