The Ulfberht swords are about 170 medieval swords found primarily in Northern Europe, dated to the 9th to 11th centuries, with blades inlaid with the inscription +VLFBERH+T or +VLFBERHT+. The word "Ulfberht" is a Frankish personal name, indicating the potential origin of the blades.
The swords are at the transitional point between the Viking sword and the high medieval knightly sword. Most have blades of Oakeshott type X. They are also the starting point of the much more varied high medieval tradition of blade inscriptions. The reverse sides of the blades are inlaid with a geometric pattern, usually a braid pattern between vertical strokes. There are also numerous blades which have this type of geometric pattern but no Vlfberht inscription.
Ulfberht swords were made during a period when European swords were still predominantly pattern welded ("false Damascus"), but with larger blooms of steel gradually becoming available, so that higher quality swords made after AD 1000 are increasingly likely to have crucible steel blades. The group of Ulfberht swords includes a wide spectrum of steel and production methods. One example from a 10th-century grave in Nemilany, Moravia, has a pattern welded core with welded-on hardened cutting edges. Another example appears to have been made from high-quality hypoeutectoid steel possibly imported from Central Asia.
The most likely place of origination of Ulfberht swords is in the Rhineland region (i.e. in Austrasia, the core region of the Frankish realm, later part of the Franconian stem duchy). Frankish origin of the swords has long been assumed because of the form of the personal name Ulfberht.
In spite of their assumed Frankish origin, the majority of the swords have been found in Northern Europe. Rather than being traded items, the swords were most likely exported as loot, ransom, or contraband - prohibitions in the Carolingian capitularia made it illegal to sell to foreigners at the time. Three specimens have been found as far afield as Volga Bulgaria (at the time part of the Volga trade route).
Number and distribution
A total of 167 Ulfberht swords have been found, mostly in Scandinavia and around the Baltic Sea. The number of swords found in Finland is unclear; Stalsberg identifies 14 Finnish Ulfberht swords, but Moilanen identifies 31. In general, the exact number of swords found is debatable due to the fragmentary condition of some artefacts, and because some inscriptions appear to be in reference to the Ulfberht type rather than indication of an actual specimen.
The prevalence of Ulfberht swords in the archaeological record of Northern Europe does not imply that such swords were more widely used there than in Francia; the pagan practice of placing weapons in warrior graves greatly favours the archaeological record in such regions of Europe that were still pagan (and indeed most of the Ulfberht swords found in Norway are from warrior graves), while sword finds in continental Europe and England after the 7th century are mostly limited to stray finds; e.g., in riverbeds. This is supported by the change in geographical distribution noted in the late Viking Age, when much of previously Pagan Europe was Christianized. None of the Norwegian Ulfberht swords are dated later than the early—middle 11th century, which coincides with the end of the end of Pagan burial rites in the area.

The original Ulfberht sword type dates to the 9th or 10th century, but swords with the Ulfberht inscription continued to be made at least until the end of the Viking Age in the 11th century. A notable late example found in Eastern Germany, dated to the 11th or possibly early 12th century, represents the only specimen that combines the Vlfberht signature with a Christian "in nomine domini" inscription (+IINIOMINEDMN). As a given name, Wulfbert (Old High German Wolfbert, Wolfbrecht, Wolfpert, Wolfperht, Vulpert) is recorded from the 8th to 10th centuries.
- According to Stalsberg (2008, p. 11, map 1) the number of swords is 14. However, according to Moilanen (2015, p. 126) the number of swords is 31. The reason for the discrepancy between the two sources is unclear, but may be due to the fragmentary nature of some specimens outlined in Moilanen.

- Wegeli (1904), p. 12, fig. 3.; Stralsberg (2008:6) classifies the "correctly" spelled inscriptions into five classes, 1. +VLFBERH+T (46 to 51 examples), 2. +VLFBERHT+ (18 to 23 examples), 3. VLFBERH+T (4 to 6 examples), 4. +VLFBERH┼T+ (1 or 2 examples), 5. +VLFBERH+T (10 examples), with a sixth class of "misspellings" (+VLEBERHIT, +VLFBEHT+, +VLFBERH+, +VLFBER├┼┼T, +VLFBERTH, 17 examples) and a seventh class "not definable" (31 or 32 examples). Stalsberg (2008) explains the numerous misspellings in the inscriptions by the "use of illiterate slaves in the smithy".
- Stalsberg (2008:2): "This indicates that geometrical and other marks were frequently welded into sword blades which have no signature, and it demonstrates that the technique of welding rods into the blade to make marks and signatures was known in many countries in Europe. This is a point to be kept in mind when discussing the question if Vlfberht blades or signatures may have been copied or falsified."
