In English it began to be used 1760s, by orientalists and linguists (Alexander Dow, William Jones), in historical contexts, and usually with a footnote identifying it with modern Persia; as recently as 1903 "Century Dictionary" defined it as "the ancient name of the region lying between Kurdistan and India." In 1935 the government of Reza Shah Pahlavi requested governments with which it had diplomatic relations to call his country Iran, after the indigenous name, rather than the Greek-derived Persia.
c. 1600, as a term in classical history, from Latin Arianus, Ariana, from Greek Aria, Areia, names applied in classical times to the eastern part of ancient Persia and to its inhabitants. Ancient Persians used the name in reference to themselves (Old Persian ariya-), hence Iran. Ultimately from Sanskrit arya- "compatriot;" in later language "noble, of good family."
Also the name Sanskrit-speaking invaders of India gave themselves in the ancient texts. Thus it was the word early 19c. European philologists (Friedrich Schlegel, 1819, who linked it with German Ehre "honor") applied to the ancient people we now call Indo-Europeans, suspecting that this is what they called themselves. This use is attested in English from 1851. In German from 1845 it was specifically contrasted to Semitic (Lassen).
German philologist Max Müller (1823-1900) popularized Aryan in his writings on comparative linguistics, recommending it as the name (replacing Indo-European, Indo-Germanic, Caucasian, Japhetic) for the group of related, inflected languages connected with these peoples, mostly found in Europe but also including Sanskrit and Persian. The spelling Arian was used in this sense from 1839 (and is more philologically correct), but it caused confusion with Arian, the term in ecclesiastical history.
The terms for God, for house, for father, mother, son, daughter, for dog and cow, for heart and tears, for axe and tree, identical in all the Indo-European idioms, are like the watchwords of soldiers. We challenge the seeming stranger; and whether he answer with the lips of a Greek, a German, or an Indian, we recognize him as one of ourselves. [Müller, "History of Ancient Sanskrit Literature," 1859]
Aryan was gradually replaced in comparative linguistics c. 1900 by Indo-European, except when used to distinguish Indo-European languages of India from non-Indo-European ones. From the 1920s Aryan began to be used in Nazi ideology to mean "member of a Caucasian Gentile race of Nordic type." As an ethnic designation, however, it is properly limited to Indo-Iranians (most justly to the latter) and has fallen from general academic use since the Nazis adopted it.
"cloth worn as a shawl by women in Iran," 1884, from Persian chadar "tent, mantle, scarf, veil, sheet, table-cloth."
1899; never defined in a generally accepted way. Early use with reference to British India; later often of everything between Egypt and Iran. Hence Middle-Eastern (1903).
The American folk custom of wearing or displaying a yellow ribbon to signify solidarity with loved ones or fellow citizens at war originated during the U.S. embassy hostage crisis in Iran in 1979. It does not have a connection to the American Civil War, beyond the use of the old British folk song "Round Her Neck She Wore A Yellow Ribbon" in the John Wayne movie of the same name, with a Civil War setting, released in 1949.
The story of a ribbon tied to a tree as a signal to a convict returning home that his loved ones have forgiven him is attested from 1959, but the ribbon in that case was white.
The ribbon color seems to have changed to yellow first in a version retold by newspaper columnist Pete Hamill in 1971. The story was dramatized in June 1972 on ABC-TV (James Earl Jones played the ex-con). Later that year, Irwin Levine and L. Russell Brown copyrighted the song "Tie a Yellow Ribbon Round the Ole Oak Tree," which became a pop hit in early 1973 and sparked a lawsuit by Hamill, later dropped.
In 1975, the wife of a Watergate conspirator put out yellow ribbons when her husband was released from jail, and news coverage of that was noted and remembered by Penne Laingen, whose husband was U.S. ambassador to Iran in 1979 and one of the Iran hostages taken in the embassy on Nov. 4. Her yellow ribbon in his honor was written up in the Dec. 10, 1979, Washington Post.
When the hostage families organized as the Family Liaison Action Group (FLAG), they took the yellow ribbon as their symbol. The ribbons revived in the 1991 Gulf War and again during the 2000s wars in Afghanistan and Iraq.
The product was used from an early date in India, Iran and northern Europe, but not in ancient Greece and Rome. Herodotus described it (along with cannabis) among the oddities of the Scythians. In old chemistry, applied to certain substances of buttery consistency. Butter-knife attested from 1818.
