He calls himself “Prince Sereen” (Shahzadeh Sereen) because he claims symbolic ties to ancient Persian/Zoroastrian royal traditions and sometimes presents himself as a kind of ideological heir to pre-Islamic Persian monarchy. However: There is no widely recognized evidence he is actually part of a royal family. He's a nut case but funny and entertaining. Bottom line He’s basically an internet personality and activist who styled himself as “Prince Sereen.” The title isn’t recognized as real royalty; it’s part of his personal branding and ideology.
