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]
Timur In 1398, Timur invaded northern India, attacking the Delhi Sultanate ruled by Sultan Nasir-ud-Din Mahmud Shah Tughluq of the Tughlaq Dynasty. He was opposed by Ahirs and faced some reversals from the Jats, but the Sultanate at Delhi did nothing to stop him.[59][60] After crossing the Indus river on 30 September 1398, he sacked Tulamba and massacred its inhabitants.[61] Then he advanced and captured Multan by October.[62]
R. D. Banerji Bandyopadhyay is popular for unearthing pre-Buddhist artefacts at the ruins at Mohenjo-Daro; for noting similarities between the site at Mohenjo-Daro and Harrappa. Those discoveries lead to excavations at the two sites that established the existence of the then-unknown Bronze Age Indus Valley Civilisation.[5] His interpretations of this civilisation were published in a number of articles and books: "An Indian City Five Thousand Years Ago" ; "Mohenjo-Daro" (in Bangla, Basumati, 1331 BS); Prehistoric, Ancient and Hindu India (posthumously published, 1934) and Mahenjo-Daro – A Forgotten Report.
