Note about search on a specific nation: results produced by this feature are incomplete and inconsistent and should be seen as a means to narrow down the list rather than anything else. Work is being done to correct mistakes and standardize the parameters. At the bottom of the list of countries are some nations that do not exist in a similar form today.

Note about search on a specific year: "ongoing armed conflict" does not imply that all of the conflicts presented for a specific year should be classified as war.

Note about search on a specific time period: finds all wars that started after a specific year (1st search parameter) and ended before a specific year (2nd param).

Note about categories: this new feature is currently being tested and the content of these categories may be incomplete or inconsistent. More categories will be added in the future.
