Although Egyptians were the dominant ethnic group in Cleopatra's kingdom, large minorities of Greeks, Jews, Celtic and Germanic peoples, Syrians, Nubians, and others inhabited Egypt during her reign and well before it.[38][39] Greeks and Jews were primarily concentrated in the multicultural cities of Alexandria, the old colony of Naukratis, and Ptolemais Hermiou (near Thebes in Upper Egypt).[40][note 9] Greeks, Jews, and Egyptians in these cities were legally segregated, living in different areas and forbidden to intermarry.[41][note 10] The native Egyptian priesthood received a number of privileges and became extremely wealthy under their Ptolemaic patrons, often becoming targets of native Egyptian revolts.[42] Although there were laws against intermarriage in the Greek city-states (poleis) of Egypt, intermarriage was permitted in other parts of Egypt;[43] Cleopatra is speculated to have had an Egyptian half-cousin, Pasherienptah III, the High Priest of Ptah at Memphis.[44] At the beginning of her reign Cleopatra sought the support and loyalty of the Egyptian priesthood, despite attempts by her rival brother and erstwhile co-ruler Ptolemy XIII to undermine this relationship.[45]
