Phoenicia was an ancient Semitic-speaking thalassocratic civilization that originated in the Levant region of the eastern Mediterranean, primarily located in modern Lebanon.
The Phoenicians came to prominence following the collapse of most major cultures during the Late Bronze Age. They developed an expansive maritime trade network that lasted over a millennium, becoming the dominant commercial power for much of classical antiquity. Phoenician trade also helped facilitate the exchange of cultures, ideas, and knowledge between major cradles of civilization such as Greece, Egypt, and Mesopotamia. After its zenith in the 9th century BC, Phoenician civilization in the eastern Mediterranean slowly declined in the face of foreign influence and conquest, though its presence would remain in the central and western Mediterranean until the second century BC.
See my reply to Lesley’s comment:
Since little has survived of Phoenician records or literature, most of what is known about their origins and history comes from the accounts of other civilizations and inferences from their material culture excavated throughout the Mediterranean.
A 2008 study led by Pierre Zalloua found that six subclades of Haplogroup J-M172 (J2)—thought to have originated between the Caucasus Mountains, Mesopotamia and the Levant—were of a “Phoenician signature” and present amongst the male populations of the “coastal Lebanese Phoenician Heartland” and wider Levant (the “Phoenician Periphery”), followed by other areas of historic Phoenician settlement, spanning Cyprus through to Morocco. This deliberate sequential sampling was an attempt to develop a methodology to link the documented historical expansion of a population with a particular geographic genetic pattern or patterns. The researchers suggested that the proposed genetic signature stemmed from “a common source of related lineages rooted in Lebanon”. Another study in 2006 found evidence for the genetic persistence of Phoenicians in the Spanish island of Ibiza.
In 2016, the skeleton of 2,500 year old Carthaginian man was excavated from a Punic tomb in Tunisia, and was found bearing the rare U5b2c1 maternal haplogroup. The lineage of this “Young Man of Byrsa” is believed to represent early gene flow from Iberia to the Maghreb.
According to a 2017 study published by the American Journal of Human Genetics, present-day Lebanese derive most of their ancestry from a Canaanite-related population (Canaanite being a pre-Phoenician name), which therefore implies substantial genetic continuity in the Levant since at least the Bronze Age. More specifically, according to geneticist Chris Tyler-Smith and his team at the Sanger Institute in Britain, who compared “sampled ancient DNA from five Canaanite people who lived 3,750 and 3,650 years ago” to modern people, revealed that 93 percent of the genetic ancestry of people in Lebanon came from the Canaanites (the other 7 percent was of a Eurasian steppe population).
In a 2020 study published in the American Journal of Human Genetics, researchers have shown that there is substantial genetic continuity in Lebanon since the Bronze Age interrupted by three significant admixture events during the Iron Age, Hellenistic, and Ottoman period, each contributing 3%–11% of non-local ancestry to the admixed population.
