Afsharid dynasty
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. Nader Shah consciously avoided the using the colour green, as green was associated with Shia Islam and the Safavid dynasty.
