"Why do the Christian nations, which were so weak in the past compared with Muslim nations begin to dominate so many lands in modern times and even defeat the once victorious Ottoman armies?"..."Because they have laws and rules invented by reason."

On the other hand, European colonial empires sometimes attempted to channel, restrict and impede trade involving their colonies, funneling activity through the metropole and taxing accordingly.

The labour shortages that resulted from abolition inspired European colonisers in Queensland, British Guaiana and Fiji (for example) to develop new sources of labour, re-adopting a system of indentured servitude. Indentured servants consented to a contract with the European colonisers. Under their contract, the servant would work for an employer for a term of at least a year, while the employer agreed to pay for the servant's voyage to the colony, possibly pay for the return to the country of origin, and pay the employee a wage as well. The employees became "indentured" to the employer because they owed a debt back to the employer for their travel expense to the colony, which they were expected to pay through their wages. In practice, indentured servants were exploited through terrible working conditions and burdensome debts imposed by the employers, with whom the servants had no means of negotiating the debt once they arrived in the colony.

The territorial boundaries imposed by European colonisers, notably in central Africa and South Asia, defied the existing boundaries of native populations that had previously interacted little with one another. European colonisers disregarded native political and cultural animosities, imposing peace upon people under their military control. Native populations were often relocated at the will of the colonial administrators.

In his critique of colonialism in Africa, the Guyanese historian and political activist Walter Rodney states:

Post-colonialism (or post-colonial theory) can refer to a set of theories in philosophy and literature that grapple with the legacy of colonial rule. In this sense, one can regard post-colonial literature as a branch of postmodern literature concerned with the political and cultural independence of peoples formerly subjugated in colonial empires.
