Approximately 2,800 American volunteers served in the Spanish Civil War on the Republican side. Confirmed indicates that I have two or more sources that place the volunteer in Spain. Those that are confirmed make up “Category I.” Category I includes both those who died in Spain and those who returned. Some of the volunteers identified as Americans are also listed on other nationality lists based on their place of birth or ethnicity. Biographical entries of Category I volunteers are listed on the ALBA website.
“Category II” volunteers lived in United States at some point prior to the Spanish Civil War, but who were neither living in the United States nor American citizens when they went to Spain. [I swapped the definition for Category II & III as they flow more logically in their current order]
“Category III”.volunteers are those who moved to the United States after participating in the Spanish Civil War.
“Unconfirmed” many names of potential volunteers have been floated throughout the years. The individuals on the unconfirmed list lack sufficient data.
Most of my work at present is devoted to the Abraham Lincoln Archives Data Base of American Volunteers and updates are primarily posted on that site.
To request information on a Category I volunteer or get in touch with me please leave a comment on the main page with your email. I will respond as quickly as possible.
