The global economic impact of the Boxer Rebellion was significant, particularly in terms of China's economic relations with the West. The uprising disrupted trade and foreign investments in China, causing a temporary but sharp decline in international confidence in the Chinese market. Following the Rebellion, the Boxer Protocol imposed large indemnities on China, which strained its economy and affected its ability to engage in independent economic development. The indemnities also led to increased foreign control over Chinese finances and customs revenues, further integrating China into the global economic system under terms largely dictated by foreign powers. This realignment of economic power dynamics in China had long-lasting effects on both its internal economic policies and its role in the global economy.

The Boer Wars had a significant impact on British colonial policy in other parts of the world. The conflicts, particularly the Second Boer War, were met with both criticism and support within Britain and internationally, leading to a reevaluation of colonial strategies. The use of concentration camps and the high cost of the war in terms of resources and human life led to a more cautious approach towards military interventions in other colonies. The aftermath of the war also saw a shift towards indirect rule and increased efforts to garner local support in colonies, as the British sought to avoid the kind of guerrilla warfare experienced in South Africa. These lessons influenced British policies in colonies like India and Egypt, where efforts were made to balance control with local administrative involvement.

The outcomes of the Anglo-German rivalry in South Africa had a profound influence on the broader geopolitical landscape of Africa. The British victory in the Boer Wars and the subsequent Treaty of Vereeniging led to the consolidation of British power in South Africa, significantly altering the balance of colonial power on the continent. This strengthened British influence in Southern Africa and cemented its position as a dominant imperial force in the region. The rivalry and its resolution also had implications for other European powers, particularly Germany, which sought to expand its own colonial territories in Africa as a counterbalance. The competition for African territories among European powers, as exemplified by the Anglo-German rivalry, was a key factor in the carving up of Africa, leading to long-term political, social, and economic consequences for the continent.

The Boxer Rebellion had a profound impact on the rise of nationalism in China. While the Rebellion itself was a manifestation of nascent nationalist sentiments against foreign domination and Christian missionaries, its suppression by international forces exacerbated these feelings. The harsh terms of the Boxer Protocol and the visible weakening of the Qing Dynasty underscored the urgency for a strong, unified China free from foreign domination. This spurred nationalist movements, including the rise of figures like Sun Yat-sen and the eventual revolution of 1911. The Rebellion can thus be seen as a catalyst that awakened a broader, more cohesive nationalist sentiment across China.

Foreign powers played a significant role in influencing China's government during the Boxer Rebellion. Following the siege of foreign embassies in Beijing, the intervention of the eight-nation alliance not only quelled the rebellion but also led to increased foreign control over China's affairs. The Boxer Protocol of 1901, imposed by the allied powers, significantly undermined China's sovereignty. It demanded large indemnities, permitted foreign troops to be stationed in Beijing, and resulted in the dismantling of Chinese forts to prevent future resistance. This intervention left the Qing government weakened and more susceptible to foreign influence, accelerating China's internal instability and hastening the decline of the dynasty.
