Indo-Greek territory. Upon his death, Menander was succeeded by his infant son Thraso, but he was apparently murdered and further civil wars ensued. Judging from their coins, many of the later kings claimed descendance from either the Euthydemids or Menander, but the details remain uncertain due to the lack of sources. The fall of Bactria From 130 BCE, the Scythians and then the Yuezhi, following a long migration from the border of China, started to invade Bactria from the north. Around 125 BCE, the Greco-Bactrian king Heliocles, was probably killed during the invasion and the Greco-Bactrian kingdom proper ceased to exist. The Indo-Greek kingdom, now entirely isolated from the Hellenistic world, did nevertheless maintain itself, if we can judge from the vast number of coins issued from the following kings, such as Lysias and Antialcidas. During this time, the Indo-Greek territory seems to have extended from the Paropamisadae and Arachosia in the west, to eastern Punjab, perhaps even with further eastern strongholds such as Mathura (see below). It is uncertain when the coastal provinces along the mouth of the Indus and further east were lost, or how tightly they were ever integrated with the kingdom. Later history Throughout the 1st century BCE, the Indo-Greeks progressively lost ground to the Indians in the east, and the Scythians, the Yuezhi, and the Parthians in the West. About 20 Indo-Greek king are known during this period, down to the last known Indo-Greek king Strato II, who ruled in the Punjab region until around 10 CE. Loss of Mathura and eastern territories (after 100 BCE) The Indo-Greeks may have ruled as far as the area of Mathura until sometime in the 1st century BCE: the Maghera inscription, from a village near Mathura, records the dedication of a well "in the one hundred and sixteenth year of the reign of the Yavanas", which could be as late as 70 BCE. Soon however Indian kings recovered the area of Mathura and south-eastern Punjab, west of the Yamuna River, and started to mint their own coins. The Arjunayanas (area of Mathura) and Yaudheyas mention military victories on their coins ("Victory of the Arjunayanas", "Victory of the Yaudheyas"). During the 1st century BCE, the Trigartas, Audumbaras and finally the Kunindas (closest to Punjab) also started to mint their own coins, usually in a style highly reminiscent of Indo-Greek coinage. The Western king Philoxenus briefly occupied most of the
