Tadmur

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.

By the third century, Palmyra had become a prosperous regional center.
