The Utah Territorial Militia Records document the administration and activities of various segments of the territorial militia, also known as the Nauvoo Legion. They were brought together by archives staff in the late 1950s and early 1960s in an effort to collect all documents about Utah veterans from any source and to serve as a state repository for those documents.
The Military Records Center acquired the documents from the late 1950s into the early 1960s, rearranging and grouping them by document type, date, and/or military district. Indexes were prepared for most of the correspondence, but plans to index all documents were never completed. These card indexes were later microfilmed and provided one of the primary ways to access these records, even with partial coverage. That microfilm has now been digitized and posted online with full text searching of the typed name information.
