who invaded south asia and set up a state following the mauryan period
Maurya Empire The fall of the Mauryas left the Khyber Pass unguarded, and a wave of foreign invasion followed. The Greco-Bactrian king, Demetrius, capitalized on the break-up, and he conquered southern Afghanistan and parts of northwestern India around 180 BCE, forming the Indo-Greek Kingdom. The Indo-Greeks would maintain holdings on the trans-Indus region, and make forays into central India, for about a century. Under them, Buddhism flourished, and one of their kings, Menander, became a famous figure of Buddhism; he was to establish a new capital of Sagala, the modern city of Sialkot. However, the extent of their domains and the lengths of their rule are subject to much debate. Numismatic evidence indicates that they retained holdings in the subcontinent right up to the birth of Christ. Although the extent of their successes against indigenous powers such as the Shungas, Satavahanas, and Kalingas are unclear, what is clear is that Scythian tribes, renamed Indo-Scythians, brought about the demise of the Indo-Greeks from around 70 BCE and retained lands in the trans-Indus, the region of Mathura, and Gujarat.[citation needed]
Western imperialism in Asia Western imperialism in Asia as presented in this article pertains to Western European entry into what was first called the East Indies. This was sparked early in the 15th century by the search for trade routes to China that led directly to the Age of Discovery, and the introduction of early modern warfare into what was then called the Far East. By the early 16th century the Age of Sail greatly expanded Western European influence and development of the Spice Trade under colonialism. There has been a presence of Western European colonial empires and imperialism in Asia throughout six centuries of colonialism, formally ending with the independence of the Portuguese Empire's last colony East Timor in 2002. The empires introduced Western concepts of nation and the multinational state. This article attempts to outline the consequent development of the Western concept of the nation state.
