The invention of the word antisemtism (Germnan: Antisemitismus) is attributed to Wilhelm Marr (1819-1904). He was a German antisemite, who founded his own anti-Jewish party in 1879. He was fed up with being called a Jew-baiter (German: Judenhetzer). He also wanted to make it clear that his hatred of the Jews was racial, not just religious and claimed that he, too, had an -ism or ideology to solve all the world's problems. (The word Antisemit (German for antisemite) is first appeared in print slightly earlier, in 1865.
The word is odd as it suggests that there is such a thing as "*semitism" that antisemites are opposed to. Like many in the 19th century, Marr named ethnic groups after languages families. However, there are no instances on record of antisemitism being used to describe hatred of others who speak a Semitic language.
