The Spanish military helmets used during the Spanish Civil War are among the most sought-after pieces in European militaria collecting. In this article, we examine the different official Spanish helmet models, their development, technical characteristics, production data and wartime use.
If you are looking to buy an original Spanish Civil War helmet for your collection, understanding the differences between the M21, M26 and M34/M38 models is essential. You can purchase an original Spanish Civil War helmet for your collection here:
During World War I, Spain remained neutral. Nevertheless, Spanish military observers closely followed the technological and tactical developments of the war, including the widespread adoption of steel combat helmets by European armies.
Unlike other nations, Spain had no immediate European enemies and its army was largely focused on internal security operations and colonial warfare in Morocco. For this reason, it continued using colonial sun helmets (salacot) and the regulation ros cap rather than adopting a steel helmet immediately after the war.
In the mid-1920s, under the 1926 Army Regulations, the Spanish General Staff began studying the adoption of a modern steel helmet to improve troop protection. An international competition was organized, and several designs were submitted. Two Spanish proposals stood out:
Although the prototype passed ballistic tests, it was initially rejected. Development continued, resulting in two definitive versions: the M26 brimless and the M26 brimmed helmets.
In 1930, approximately 12,000 units of the brimless version (commonly known among collectors as the M21) and 1,500 units of the brimmed version were produced.
In 1931, a further 20,000 helmets were manufactured, this time exclusively of the brimmed M26 type.
That same year, the monarchy ended and the Second Spanish Republic was proclaimed. Political instability during the Republic — including the 1934 Revolution and violent clashes in Asturias and Catalonia — led to the development of a lighter helmet for security forces.
In July 1936, following the uprising led by Francisco Franco, the Civil War began. At that time, three main Spanish helmet models were in service: M34 / M38, M21 / M26 “Brimless”,M26 “Brimmed”.
The M26 brimless helmet, commonly referred to as the M21 by collectors, is one of the most distinctive Spanish Civil War helmets. The reason for the M21 designation is unknown and somewhat confusing, yet it remains the most commonly used term.
Originally factory-painted grey, many examples were repainted during the Civil War in green or khaki. Period photographs show numerous helmets decorated with militia insignia, slogans and political symbols from both Republican and Nationalist forces.
Due to repainting and postwar refurbishment, untouched original examples are increasingly rare.
M26 “Brimmed” Helmet
The M26 brimmed helmet represents the more developed version of the Spanish Model 1926.
Like the brimless version, it was originally painted grey and later repainted during wartime.
The brimmed model eventually became the dominant Spanish Army helmet before and during the early stages of the Civil War.
The M34 (production year) or M38 (distribution year) was developed from 1934 primarily for State Security Forces.
However, due to shortages of steel helmets during the Civil War, it was also used in combat roles.
Ballistic protection was inferior to the M26, being designed primarily for lighter threats.
After the end of the Spanish Civil War, the Francoist regime launched a recovery campaign to re-equip the new army. All three helmet models were refurbished and reissued.
Refurbishment typically included:
With the 1943 Regulation, a front clip was added to hold the Spanish Army eagle emblem (eagle with the Cross of Saint James, not to be confused with the Eagle of Saint John).
Although later replaced by the Z-42 helmet, the M21, M26 and M34/M38 remained in service into the 1950s and, in some cases, even into the 1970s.
Spanish Civil War helmets are highly valued in militaria collecting for several reasons:
As a precursor to World War II, the conflict also served as a testing ground for the Soviet Union, the International Brigades, Nazi Germany and Kingdom of Italy, increasing international historical interest.
Because many helmets were repainted, captured, modified at the front, or refurbished after the war, finding completely original, untouched Spanish Civil War helmets today is exceptionally difficult — which significantly increases their collector value.
BEWARE! The market is full of helmets repainted with colorful drawings and slogans from both the Republican and Francoist sides; most of them are modern restorations.
