The growth of nationalism in colonies is closely linked to the emergence of anti-colonial movements. This can be attributed to several factors, ranging from the experience of colonial rule to the aspirations for self-determination and independence. The following points elaborate on this connection:

Colonial Suppression and Exploitation:
1. Under colonial rule, colonies were often subjected to suppression, discrimination, and exploitation by the colonizers. This led to a sense of injustice and resentment among the colonized population.
2. Economic exploitation, including the extraction of resources and forced labor, further fueled the desire for independence and the rejection of colonial rule.
3. Political repression, denial of basic rights, and cultural assimilation efforts by the colonizers also contributed to the growth of nationalism as a means to reclaim identity and autonomy.

Emergence of Nationalist Leaders and Organizations:
1. Nationalist leaders emerged within the colonies, advocating for the rights and interests of their own people. These leaders played a crucial role in mobilizing the masses and fostering a sense of national identity.
2. Nationalist organizations, such as the Indian National Congress in India or the African National Congress in various African countries, provided platforms for political activism and the articulation of nationalist aspirations.

Influence of Global Movements:
1. The rise of global movements, such as decolonization and anti-imperialism, had a significant impact on colonial societies. The successful struggles for independence in countries like India, Indonesia, and Algeria inspired nationalists in other colonies to challenge their own colonial rulers.
2. Ideas of self-determination, democracy, and human rights gained prominence during this period, further strengthening the anti-colonial sentiment.

Formation of Alliances and Solidarity:
1. Nationalist movements in different colonies often formed alliances and established networks of solidarity. They recognized the common struggle against colonialism and sought support from each other.
2. These alliances allowed for the exchange of ideas, strategies, and resources, accelerating the anti-colonial movement and contributing to the eventual downfall of colonial powers.

Conclusion:
The growth of nationalism in colonies is intricately connected to the anti-colonial movement due to the experiences of suppression and exploitation, the emergence of nationalist leaders and organizations, the influence of global movements, and the formation of alliances and solidarity. Nationalism served as a powerful force in mobilizing people, demanding independence, and reclaiming their rights and identities.
