This is a maintenance category.
Profiles are added here when the template {{US Civil War|Needs=PPP}} is added to a profile.
After review by project leaders, the profile will either be set as Project Protected, or noted why it does not meet the criteria, and the template on the profile will be updated to reflect {{US Civil War}} if PPP or removed if not.
This category is managed by the US Civil War Project in association with the Categorization Project. For assistance with this or related categories ask in G2G making sure to tag your question with both categorization and US_Civil_War.
