We appreciate your help in curating these events from OpenHistoricalMap data. Items should be based on fully qualified start_date=* and end_date=* tags, plus any other metadata tagged on features in OpenHistoricalMap. To the extent possible, the list should feature a wide range of years and include events from different continents.
