The Lion and Sun or Shir-o-khorshid (Persian: شیر و خورشید) is one of recognized emblems of the Red Cross Movement alongside Red Cross and Red Crescent. It is one of the better-known emblems of Iran, and between 1423 and 1979 was an element in Iran's national flag. The motif, which combines ancient Iranian, Arab, Turkish, Mongol and Jewish traditions, became a popular symbol in Iran in the 12th century. The lion and sun symbol is based largely on astronomical and astrological configurations: the ancient sign of the sun in the house of Leo, which itself is traced backed to Babylonian astrology and Near Eastern traditions. The motif has many historical meanings. First, it was only an astrological and zodiacal symbol. Under Safavid and the first Qajar kings, it became more associated with Shia Islam. During the Safavid era, the lion and sun stood for the two pillars of society, the state and the Islamic religion. It became a national emblem during the Qajar era. In the 19th century, European visitors at the Qajar court attributed the lion and sun to remote antiquity; since then, it has acquired a nationalistic interpretation. During the reign of Fat'h Ali Shah and his successors the form of the motif was substantially changed. A crown was also placed on the top of the symbol to represent the monarchy. Beginning in the reign of Fat'h Ali Shah Qajar, the Islamic aspect of the monarchy was de-emphasized. This shift affected the symbolism of the emblem. The meaning of the symbol changed several times between the Qajar era and the 1979 revolution. The lion could be interpreted as a metaphor for Ali, for the heroes of Iran who are ready to protect the country against enemies, or for its ancient meaning as the symbol of kingship. The Sun has alternately been interpreted as symbol of the king, Jamshid, the mythical king of Iran, and the motherland. The many historical meanings of the emblem have provided rich ground for competing symbols of Iranian identity. In the 20th century, some politicians and scholars suggested that the emblem should be replaced by other symbols such as Derafsh-e-kaviani. However, the emblem remained the official symbol of Iran until the 1979 revolution, when the "Lion and Sun" symbol was removed from public spaces and government organizations, and replaced by the present-day Emblem of Iran.
