The Battle of Dandanaqan (Persian: نبرد دندانقان) was fought in 1040 between the Seljuq Turkmens and the Ghaznavid Empire near the city of Merv (now in Turkmenistan).[6][7] The battle ended with a decisive Seljuq victory, which subsequently brought down the Ghaznavid domination in Greater Khorasan. War elephants were used by the hundreds.
