The Historical Context event lists are CSV lists of dated Historical Events (with the semicolon as the delimiter) that are loaded and compared against the lifespan (birth year through death year) of the Active Person. These seven files come with the addon and can be changed with any editor that saves in plain text. :* [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/default_data_v1_0.txt <code>default_data_v1_0.txt</code>] - combined list of historic events* [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/pandemi_v1_0.txt <code>pandemi_v1_0.txt</code>] - list of Pandemic Events (after 1500 CE)* [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/da_DK_data_v1_0.txt <code>da_DK_data_v1_0.txt</code>] - list of Dansk historical events* [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/en_US_data_v1_0.txt <code>en_US_data_v1_0.txt</code>] - list of USA Presidential terms * [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/HistContext/en_US_involuntary_v1_0.txt <code>uk_UA_data_v1_0.txt</code>] - list of Ukrainian historical events* [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/HistContext/en_US_involuntary_v1_0.txt <code>en_US_involuntary_v1_0.txt</code>] - involuntary commitment policies in the USA* [https://github.com/gramps-project/addons-source/blob/maintenance/gramps52gramps60/HistContext/en_US_prejudice_v1_0.txt <code>en_US_prejudice_v1_0.txt</code>] - socio-political prejudice trends in the USA* If you have created a custom Event file (named <code>custom_v1_0.txt</code>) it will be shown.

If you have created ===== CSV format =====You can create a custom Event file (named <code>custom_v1_0.txt</code>) then and those Events will be merged into the list. {{man menu|After creating the custom Event file, adding it as a Media object means the file will be included in backups with media. And if the default viewer for .txt files is a text editor instead of a simple view, then you can use Gramps to add or remove Events from its historical event list.}}

For Events that only last one year, enter the same year for both start and end date. For ongoing Events, use <code>Today</code> for the end year. If either of the dates are missing, the gramplet assumes a life span lifespan of the Preferences limit for "Maximum age probably alive".

When entering a URL from services like wikipediaWikipedia, remove the subdomain language (i.e., <code>en.</code> for englishEnglish) or platform (e.g., <code>m.</code> for mobile indicator subdomain). This allows wikipedia Wikipedia to adapt to the target machine.

The customizations for this Gramplet are stored in 3 locations: a common <code>HistContext.ini</code> the the gramplet's folder, distributed splitbar <code>.ini</code> files for each view mode (e.g., <code>People_personlistview_sidebar.ini</code> in the <code>gramps/gramps{{Stable_branch}}</code> folder) and the <code>gramps.ini</code> file in the [[Gramps_Glossary#user_directory|Gramps User Directory]].

Configuration options are saved in the HistContext.ini found in the addon's subdirectory in the gramps/gramps{{Stable_branch}}/HistContext.ini file. Once the {{man menu|View -> Configuration }} is uses and saved, there will be <code>HistContext.ini</code> in the addon folder with the options:
