The White Man's Burden is a poem by Rudyard Kipling. Although the poem has deeper meanings, a direct reading was popularized from the dominant points of view at the time, justifying as a noble enterprise, an ungrateful and altruistic obligatio, the domain of " white man" on those defined as "inferior races".
Apparently, in a superficial reading, the subject is a rhetorical mandate to the white man to colonize the other races for the benefit of them, being their "burden" both the task and the people themselves to colonize. Because of this issue, as well as the resounding title, it soon became an emblem of colonial rule and white supremacists.
Angkor Wat is a temple complex built in the Khmer Empire and is the largest religious monument in the world. It was built in the early 12th century and was first a Hindu temple and then a Buddhist temple. It was the capital of the Khmer Empire when King Suvayarman II ruled and made it his state temple and then eventually became his mausoleum. It is Cambodia's most visited site.
