Sites featuring horse burials are found throughout the regions of the world occupied by Indo-Aryan, Turkic, and Chinese peoples. They include Tall al-Ajjul (Gaza strip, dating back to 2100 BC), Central Iran, where horse burials are attested in the second millennium BC, Marlik (in Iran, from the late second millennium BCE), and Gordium (in Phrygia, with horse burials attested possibly after 700 BCE). A horse burial from Bactria provides evidence of the migration in the second millennium BCE of horse cultures from Central Asia into Turkmenistan. A horse burial in Tell el-Dab'a, Egypt, evidences the introduction of the horse to Egypt by the Hyksos, in the Second Intermediate Period of Egypt (1650–1550 BCE).
