olonial rule had a profound effect on Southeast Asia. While the colonial powers profited much from the region’s vast resources and large market, colonial rule did develop the region to a varying extent. Commercial agriculture, mining and an export based economy developed rapidly during this period. Increased labor demand resulted in mass immigration, especially from British India and China, which brought about massive demographic change. The institutions for a modern nation state like a state bureaucracy, courts of law, print media and to a smaller extent, modern education, sowed the seeds of the fledgling nationalist movements in the colonial territories. In the inter-war years, these nationalist movements grew and often clashed with the colonial authorities when they demanded self-determination.
