Popular sovereignty was among the main principles of imperialism.

This principle asserted that the authority and power of a government is derived from the consent and will of the people it governs. In the context of imperialism, this principle was often used to justify the colonization and domination of other territories and peoples. Imperial powers claimed that they were bringing civilization and progress to less developed regions, and that the local populations would ultimately benefit from being ruled by a more advanced and powerful nation.

However, in practice, popular sovereignty was often disregarded in imperialist endeavors, as the interests of the colonized populations were frequently ignored or suppressed in favor of the goals and ambitions of the imperial powers. This led to widespread exploitation, oppression, and resistance among colonized peoples, as they sought to assert their own sovereignty and independence. Ultimately, the principle of popular sovereignty was often used as a facade to justify and legitimize the unjust and exploitative practices of imperialism.
