How did the On-Ogur tribal confederation influence the name Hungary?

The name "Hungary" is derived from the On-Ogur tribal confederation, a term meaning "ten tribes" or "ten arrows" that described the federation of Magyar and Turkic Khazar tribes.12

While the Hungarians refer to themselves as magyar, Western names for the country—such as the French hongrois, German Ungar, and Russian vengr—evolved from the Slavic pronunciation of On-Ogur. The initial "H" was later added to the name because some scholars incorrectly associated the people with the ancient Huns.12
