The Afsharid dynasty (1736–1796) had two royal standards, one with red, white, and blue stripes and one with red, blue, white, and yellow stripes. Nader Shah's personal flag was a yellow pennant with a red border and a lion and sun emblem in the centre. All three of these flags were triangular in shape.[24][25] Nader Shah consciously avoided the using the colour green, as green was associated with Shia Islam and the Safavid dynasty.[26]
