The Sons of Union Veterans of the Civil War was a creation of the Grand Army of the
Republic (GAR) which was formed in 1866. Wanting to pass on its heritage, the GAR
in Philadelphia, Pennsylvania created a Corps of Cadets in 1878 which later became
the Sons of Veterans of the United States of America (SV). This latter organization
was formed in Pittsburgh, Pennsylvania on November 12, 1881. The SV units functioned
much as National Guard units and actually served along with state militia during
the Spanish American War.
In 1904, the SV elected to become a patriotic education society and in 1925 changed
its name to Sons of Union Veterans of the Civil War (SUVCW). However, to keep the
military aspect alive, the SUVCW created within the organization the Sons of Veterans
Reserve (SVR) which was carried on the Army rolls as a Reserve contingent. Some SVR
units served with the Army during World War I. After World War I, the SVR was listed
as a training company of the U.S. Army.
In more recent years, the SVR's mission has become historic, ceremonial, and commemorative.
Prior to disbanding and before the death of its last member, the GAR officially designated
the SUVCW as its successor and heir to its remaining property. On August 20, 1954,
the SUVCW was officially incorporated by an Act of Congress by the passing of Public
Law 605 of the second session of the 83rd Congress.
