- Menander I Soter (ruled c. 155/150 – 130/120 BC) was an Indo-Greek king whose vast kingdom stretched from Gandhara and Punjab to nearly the Indus valley. - Patanjali's Mahabhasya, a work from the Sunga period, mentions a Greek (Yavana) invasion reaching Saketa (near Ayodhya) and Madhyamika (near Chittorgarh). - While the exact date and extent of Menander's conquests are debated, he is the most likely figure among the options to have led such an invasion during the Sunga period.
