What happen in Nineteenth century from year (1815-1914)?

The world changed profoundly in the nineteenth century. Economic, political, social, cultural and technological factors interacted in complex ways to transform societies and reshape external relations. Economists identify three types of movement or ‘flows’ within international economic exchanges. The first is the flow of trade which in the nineteenth century referred largely to trade in goods (e.g., cloth or wheat). The second is the flow of labour – the migration of people in search of employment. The third is the movement of capital for short-term or long-term investments over long distances. All three flows were closely interwoven and affected peoples’ lives more deeply now than ever before. The interconnections could sometimes be broken – for example, labour migration was often more restricted than goods or capital flows.
