India was conquered beginning with 1757, much after Latin America. Industrial revolution began a few decades later with the invention of steam engine, spinning jelly, etc., only during the 1780's and onwards. It was therefore only with the colonisation that the decline of countries like India begins. In a few decades the west had established absolute supremacy in most fields over the countries of what now are called the "third world". Some writers like Andre Gunder Frank have called this as the process of the "development of underdevelopment."
