The period of New Imperialism, also known as Neo-Imperialism, emerged in the late 19th and early 20th centuries as a second wave of imperialism, distinct from earlier waves of European colonization. This phase was significantly influenced by the Industrial Revolution and was characterized by heightened competition among industrialized nations for dominance and exploitation of non-industrialized regions.

Several key factors contributed to the rise of New Imperialism:

1. Role of Political Factors: The rise of Absolute Monarchies in Italy and Germany post-unification in the 1870s played a role in increasing the aggression of states. However, it's important to note that both democratic and absolute regimes engaged in imperialism. Industrialization amplified their capacity and desire to build colonial empires. Rulers viewed imperialism as a means to maintain political control domestically.
2. Role of Nationalism: Nationalism gained momentum after the French Revolution in 1789. In the era of industrialization, it transformed into economic rivalry among nation-states. Nationalist ideas, propagated by thinkers, fueled national rivalries. In countries like Britain, France, Germany, and Italy, nationalism led to demands for the expansion of colonial empires during 1868-72.
3. Role of Industrial Revolution/Industrial Capitalism: The Industrial Revolution was a major catalyst for the rise of New Imperialism. The surplus generated from trade and profits from mass production was reinvested for capital formation. The development of transport and communication infrastructure facilitated faster movement of goods and people. Steamships reduced trading time globally. Factories' demand for raw materials surged, leading to a quest for resources beyond national borders.
4. Increased Number of Players: Industrialization spread to the rest of Europe, the USA, and Japan after the 1870s. This led industrialized nations to intensify their search for raw materials and new export markets.
5. Decreased Geographical Space: By the 19th century, much of the world had already come under the influence of powerful nations. Further expansion could only happen at the expense of other colonial powers, leading to increased competition and the need for tighter control over existing colonies.
6. Religion and Cultural Factors: The aspirations of Christian missionaries to spread Christianity, along with the notion of the "White Man's burden" to bring superior civilization to "backward" colonies, played a role. Some viewed these missions as a pretext for exploitation, while others genuinely worked for social reforms and upliftment.

New Imperialism marked a period of intense geopolitical rivalries, as industrialized nations vied for global dominance and established vast colonial empires. The competition for colonies and spheres of influence, driven by economic interests and political ambitions, had far-reaching consequences for the world.

During the era of New Imperialism, several rising powers emerged and actively engaged in the expansion of their colonial territories. Here's an overview of the key powers and their imperialist activities:

1. Italy:
• Beginning of Industrialization proper: From 1870 onward
• Victims of New Imperialism: Mainly Africa
2. Germany:
• Beginning of Industrialization proper: From 1870 onward
• Victims of New Imperialism: Mainly Africa, Pacific
3. Russia:
• Beginning of Industrialization proper: From the 1850s onward
• Note: By the eve of World War I, Russia's economy was still predominantly agricultural.
• Victims of New Imperialism: Mainly Central Asia, West Asia, China
4. USA:
• Beginning of Industrialization proper: By the 1890s
• Victims of New Imperialism: Mainly Pacific (with a focus on the domination of South America)
5. Japan:
• Beginning of Industrialization proper: By the 1890s
• Victims of New Imperialism: Mainly China (in the Far East) and Pacific

These rising powers, driven by industrialization and economic interests, sought to expand their influence and territories through imperialistic endeavors. Their activities had significant global ramifications, leading to the establishment of colonial empires and shaping the geopolitical landscape of the late 19th and early 20th centuries.
