Query for historical eventsHi, I am trying to write a query which would show the most significant historical events and display country, date, coordinates, significant people. I would like to limit it to a couple of thousand lines, however I am having trouble with defining historical event. So far a have a query which shows an event, country, date. I tried "point in time: 5th century" or "instance of: history of the world", but they don't filter my query. Could someone please help me in defining the historical events?
