Khokrakot (modern Rohtak), belonging to as many as 14 different Indo-Greek kings, as well as coin molds in Naurangabad, suggesting Indo-Greek occupation of Haryana in the 2nd-1st centuries BC. An inscription in Mathura discovered in 1988, the Yavanarajya inscription, mentions "The last day of year 116 of Yavana hegemony (Yavanarajya)". The "Yavanarajya" probably refers to the rule of the Indo-Greeks in Mathura as late as around 70–60 BC (year 116 of the Yavana era). The extent of Indo-Greek rule in Mathura has been disputed, but it is also known that no remains of Sunga rule have been found in Mathura, and their territorial control is only proved as far as the central city of Ayodhya in northern central India, through the Dhanadeva-Ayodhya inscription. Archeological excavations of cast die-struck coins have also revealed the presence of a Mitra dynasty (coin issuers who did not name themselves "kings" on their coins) in Mathura sometime between 150 BC to 20 BC. Additionally, coins belonging to a Datta dynasty have also been excavated in Mathura. Whether these dynasties ruled independently or as satraps to larger kingdoms is unknown. Figurines of foreigners in Mathura Several figures of foreigners appear in the terracottas of Mathura art from the 4th to the 2nd century BCE, which are either described simply as "foreigners" or Persian or Iranian because of their foreign features. These figurines might reflect the increased contacts of Indians with foreigners during this period. Several of these seem to represent foreign soldiers who visited India during the Mauryan period and influenced modellers in Mathura with their peculiar ethnic features and uniforms. A helmeted head of a soldier, probably Indo-Greek, is also known, and dated to the 1st century BCE, now in the Mathura Museum. One of the terracotta statuettes, usually nicknamed the "Persian nobleman" and dated to the 2nd century BCE, can be seen wearing a coat, scarf, trousers and a turban. Mathura may then have been conquered by the Mitra dynasty, or ruled independently by the Datta dynasty during the 1st century BC. In any case Mathura was under the control of the Indo-Scythian Northern Satraps from the 1st century of the Christian era. Indian sources The term Yavana is thought to be a transliteration of "Ionians" and is known to have designated Hellenistic Greeks (starting with the Edicts of Ashoka, where Ashoka writes about "the Yavana king Antiochus"), but may have sometimes referred to
