Who was involved in imperialism during the industrial revolution

The Industrial Revolution also made Europeans more capable of conquering large parts of the world. European improvements in weapons made unindustrialized nations easier to defeat in battle. Steamboats and railroads made Europeans more capable of projecting power to far-flung colonies, which permitted the European powers to control larger areas. Improvements in transportation also gave Europeans better access to distant markets, giving them a place to sell the manufactured goods that they made with their new technology.
