Arabic-speaking desert nomads of the Middle East are known as bedouin. Ethnically, the bedouin are identical to other Arabs. Bedouin social rank is determined by the animals they herd: camel nomads are most prestigious, followed by sheep and goat herders, and finally cattle nomads. Avdat is the site of a ruined Nabataean city in the Negev desert in southern Israel. It was the most important city on the Incense Route after Petra, between the 1st century BCE and the 7th century CE.
