Marg bar Amrika, often transliterated as Marg bar Amirka, is a Persian political slogan that has been chanted at rallies and demonstrations in Iran since the 1979 revolution. It translates literally as death to America and has long been associated with anti-American protests, state-organised marches and wider criticism of United States foreign policy. Short recordings of the chant circulate online as reaction audio because the phrase is instantly recognisable, even to listeners who do not speak Persian, and because its rhythmic crowd delivery makes it easy to drop into edited clips about geopolitics.
