What tactics did they use? Did they alter their objectives and tactics over time? Then imagine how imperialist might work with those whom they dominated. What did they hope to accomplish? How did they view those whom they ruled? What sort of concessions were they willing to make to secure cooperation? Did their objectives and tactics vary over time? Again, use specific examples to illuminate the subject.

To determine the specific tactics used by imperialist powers, it is necessary to focus on a particular time period and specific colonial power. For the purpose of this response, let's consider the British Empire during the 19th and early 20th centuries.

1. Tactics used by Imperialist powers:
a) Military Force: Imperial powers often employed military force to establish control over territories. The British Empire, for example, used its powerful navy to dominate trade routes and establish colonies worldwide.
b) Economic Exploitation: Imperial powers exploited the resources of the territories they dominated, often establishing lucrative plantations or mines. British imperialists extracted resources such as rubber, tea, and minerals from their colonies for economic gain.
c) Cultural Assimilation: Imperial powers aimed to spread their culture, language, customs, and religion among the populations they ruled. British imperialists sought to Anglicize the colonies and spread Christianity.
d) Administrative Control: Expanding empires needed efficient administration. Imperial powers established bureaucratic systems and implemented legal and political frameworks to govern their colonies.

2. Alteration of objectives and tactics over time:
Objectives and tactics employed by imperial powers did evolve over time. Initially, the emphasis was on establishing direct control through colonization. However, as nationalist sentiments grew stronger in the colonies, imperial powers shifted to indirect rule, granting greater autonomy to local leaders while still maintaining control over key areas such as defense and foreign policy. This approach aimed to co-opt local elites and reduce resistance.

3. Relations with those dominated by imperialism:
Imperial powers generally approached their subjects from a perspective that often reinforced racial and cultural hierarchies. British imperialists, for instance, viewed the populations they ruled as inferior and often used discriminatory policies to maintain control. Their objective was to exploit the resources and labor of the colonies for the benefit of the imperial power rather than genuinely seeking to improve the conditions for the local population.

4. Concessions made to secure cooperation:
Imperial powers frequently made concessions to secure cooperation from local populations or elites. These concessions could manifest as economic benefits, protection of certain cultural practices, or limited political representation. For example, the British Empire sometimes allowed local rulers to retain their positions of authority within the colonial administration to ensure compliance and cooperation.

5. Variation of objectives and tactics over time:
As mentioned earlier, the objectives and tactics of imperial powers did vary over time according to changing circumstances. Initially, the primary objective was sheer territorial acquisition and resource exploitation. However, as nationalist movements gained strength, imperial powers shifted towards assimilation, indirect rule, or a strategy of divide-and-rule to quell dissent and maintain control.

It is important to note that this response provides a broad overview of the tactics and objectives of imperialist powers, specifically focusing on the British Empire. The nuances, regional variations, and complexities of imperialism require in-depth analysis and consideration of specific cases.
