What was the connection between the English Industrial Revolution and the rise of imperialism?

Imperialism in Asia traces its roots back to the late fifteenth century with a series of voyages that sought a sea passage to India in the hope of establishing direct trade between Europe and Asia in spices. Before 1500 European economies were largely self-sufficient, only supplemented by minor trade with Asia and Africa. Within the next century, however, European and Asian economies were slowly becoming integrated through the rise of new global trade routes; and the early thrust of European political power, commerce, and culture in Asia gave rise to a growing trade in lucrative commodities—a key development in the rise of today's modern world free market economy.

In the sixteenth century, the Portuguese established a monopoly over trade between Asia and Europe by managing to prevent rival powers from using the water routes between Europe and the Indian Ocean. However, with the rise of the rival Dutch East India Company, Portuguese influence in Asia was gradually eclipsed. Dutch forces first established independent bases in the East (most significantly Batavia, the heavily fortified headquarters of the Dutch East India Company) and then between 1640 and 1660 wrestled Malacca, Ceylon, some southern Indian ports, and the lucrative Japan trade from the Portuguese. Later, the English and the French established settlements in India and established a trade with China and their own acquisitions would gradually surpass those of the Dutch. Following the end of the Seven Years' War in 1763, the British eliminated French influence in India and established the British East India Company as the most important political force on the Indian Subcontinent.

Before the Industrial Revolution in the mid-to-late nineteenth century, demand for oriental goods remained the driving force behind European imperialism, and (with the important exception of British East India Company rule in India) the European stake in Asia remained confined largely to trading stations and strategic outposts necessary to protect trade. Industrialisation, however, dramatically increased European demand for Asian raw materials; and the severe Long Depression of the 1870s provoked a scramble for new markets for European industrial products and financial services in Africa, the Americas, Eastern Europe, and especially in Asia. This scramble coincided with a new era in global colonial expansion known as "the New Imperialism," which saw a shift in focus from trade and indirect rule to formal colonial control of vast overseas territories ruled as political extensions of their mother countries. Between the 1870s and the beginning of World War I in 1914, the United Kingdom, France, and the Netherlands — the established colonial powers in Asia — added to their empires vast expanses of territory in the Middle East, the Indian Subcontinent, and South East Asia. In the same period, the Empire of Japan, following the Meiji Restoration; the German Empire, following the end of the Franco-Prussian War in 1871; Tsarist Russia; and the United States, following the Spanish-American War in 1898, quickly emerged as new imperial powers in East Asia and in the Pacific Ocean area.

The English Industrial Revolution (EIR from now on) was the rise of technology, weapons manufacturing, and the cottage industry. This was the cause of some neighboring countries asking themselves, "what are they doing, and why are they making so many weapons?" you see what i mean? this then caused neighboring countries who were already on unstable grounds with the English to think that they were about to try and expand. the unstable countries automatically assumed the worst, and started expanding themselves in order to keep their own power. Do you see where this is going? the expanding countries then went on a conquering spree and liked the idea of more power. England then took to the idea and practically took over Africa and much of the rest of the Europe, and some of South America, hence the quote, "The sun never sets on the English Empire."
