One iteration of the Keffiyeh is referred to as the Palestinian keffiyeh which commonly appears in a black-and-white check iteration; they also appear in different colours including red-and-white and non-checkered patterns. It was traditionally associated with rural farmers who worked under Ottoman rule but became a signifier of Palestinian nationalism following the 1936–1939 Arab Revolt in Palestine. It has maintained prominence throughout the rest of the 20th and into the 21st century and is colloquially cited as Palestine's 'unofficial flag' and a Palestinian political symbol.
