Palmyrene Aramaic language in the context of Vaballathus

Palmyra (/pælˈmaɪrə/ pal-MY-rə; Palmyrene Aramaic: 𐡶𐡣𐡬𐡥𐡴‎, romanized: Tadmor; Arabic: تَدْمُر‎, romanized: Tadmur) is an ancient city in central Syria. It is located in the eastern part of the Levant, and archaeological finds date back to the Neolithic period, and documents first mention the city in the early second millennium BCE. Palmyra changed hands on a number of occasions between different empires before becoming a subject of the Roman Empire in the first century CE.

The city grew wealthy from trade caravans; the Palmyrenes became renowned as merchants who established colonies along the Silk Road and operated throughout the Roman Empire. Palmyra's wealth enabled the construction of monumental projects, such as the Great Colonnade, the Temple of Bel, and the distinctive tower tombs. Ethnically, the Palmyrenes combined elements of Amorites, Arameans, and Arabs. Socially structured around kinship and clans, Palmyra's inhabitants spoke Palmyrene Aramaic, a variety of Western Middle Aramaic, while using Koine Greek for commercial and diplomatic purposes. The Hellenistic period of West Asia influenced the culture of Palmyra, which produced distinctive art and architecture that combined different Mediterranean traditions. The city's inhabitants worshiped local Semitic, Mesopotamian, and Arab deities.

Septimia Zenobia (Palmyrene Aramaic: 𐡡𐡶𐡦𐡡𐡩‎, romanized: Bat-Zabbai; c. 240 – c. 274) was a third-century queen of the Palmyrene Empire in Syria. Many legends surround her ancestry; she was probably not a commoner, and she married Odaenathus, the ruler of the city of Palmyra. Her husband became king of Palmyra in 260, elevating Palmyra to supreme power in the Near East by defeating the Sasanian Empire of Persia and stabilizing the Roman East. After Odaenathus' assassination in 267, Zenobia became the regent of her son Vaballathus and held de facto power throughout his reign (267 to 272).

In 270, Zenobia launched an invasion that brought most of the Roman East under her sway and culminated with the annexation of Egypt. By mid-271 her realm extended from Ancyra, central Anatolia, to Upper Egypt, although she remained nominally subordinate to Rome. However, in reaction to the campaign of the Roman emperor Aurelian in 272, Zenobia declared her son emperor and assumed the title of empress, thus declaring Palmyra's secession from Rome. The Romans were victorious after heavy fighting; the empress was besieged in her capital and captured in late 272 by Aurelian, who exiled her to Rome, where she spent the remainder of her life.
