Reinhold is of Germanic origin, derived from the elements 'ragin' meaning "advice" and 'wald' meaning "rule". It was popularized by Reinhold von Breitenlandenberg, a 12th-century German knight who participated in the Third Crusade. The name Reinhold was introduced to England during the Norman Conquest but remained relatively uncommon until the mid-19th century when it began to gain popularity in Germany and other parts of Europe. Today, Reinhold is still considered a distinctive and strong-sounding name.
The name Reinhold experienced significant fluctuations in popularity over time, with a notable peak during World War I. Between 1912 and 1919, there were at least 30 births each year, reaching a high of 72 births in 1917. However, after the war, the number of Reinhold births declined dramatically, dropping to single digits by the early 1930s. This trend continued until the late 1950s and early 1960s when there were occasional years with around 10 births. Since then, the name has remained relatively uncommon, with only a handful of births recorded each year. In total, over 1431 children named Reinhold were born between 1882 and 1988.
