Alternatively, an "ethnic flag" may represent a Pan-nationalism, such as the Pan-Arab flag which originates as the flag of the Arab Revolt during World War I, the proposed flag of Pan-Slavism (1848), Pan-Iranism or Pan-Turkism. The concept of using ethnic flags to symbolize ethnic groups within a multiethnic state, not necessarily connected with irredentism, became popular in the later 20th century, such as the Australian Aboriginal flag (1971), the Assyrian flag (1971), the flag of the Romani people (1971), the Berber flag (1970s), the Sami flag (1986)
