Original Title: TIL In the 1590s, a Spanish admiral made up an entire nation, complete with dozens of fake coats of arms, so that he could claim to be a nobleman and join a fraternity of knights. In doing so, he accidentally popularized the pan-South-Slavic movement, and caused the founding of Yugoslavia in 1918.
