I understand how our knowledge of the past is constructed through analysis of primary sources of many kinds

For something to be a primary source, it would be created during the time that you're looking at. Examples include letters, diaries, posters, documents, and other artifacts. Primary sources can be used to prove certain things that have happened. They also, most importantly, give an inside look at what was going on during that time. These reasons are what make primary sources better than others. Text books and other secondary sources like that get most or all of their information from primary sources. Primary sources are necessary for us to understand things that happened before us. If in 100 years a class was given a project to research the 2000's then the things that we write and make and record would be primary sources to them because we are the one's living now.

"The White Man's Burden"
This is a Pear's Soap advertisement printed during the New Imperialism. It shows the general attitude of the West at the time, claiming that "teaching the virtue of cleanliness is the first step towards lightening 'The White Man's Burden.'" It goes on to talk about 'brightening the dark corners of the earth.' I know that this website is credible because of the -.org ending, the article's author cites all of their information, and he lists his credentials at the top.

"White Man's Burden"

This is artwork from the 1800's. It displays that same old idea of the white man's burden, because it was such a prominent aspect in people's lives back then, but this time directed at Japanese people. There were many cartoons like this, white people pretty much looked down on everyone else. The website is an appropriate source, you can tell because it is professional-looking and has a -.org ending.

British India---1850's

This photograph was taken in India, back when the British were pretty much running the country and had colonies all over the place, a perfect example of New Imperialism. The British had colonies in other places too. I found the website is an appropriate source because of the -.net ending and the professionalism of the website, it has a huge old gallery of other pictures. I thought this other picture fit very well but I couldn't find a good source for it. The British man is in India, getting a pedicure from some of his Indian servants. It gives a really good picture of how white people thought of others.

A British Man Gets a Pedicure from an Indian Servant

See Malaya This was a travel poster urging British people to go see their colony in Malaysia. The colony was a major source of money and natural resources for the British. To make people want to go there, it was portrayed as tropical and vacation-y. The picture is of a 'native' Malaysian. The British had their colony there during their quest for power and land in the New Imperialism. The -.org website looks reliable enough to use for a source, it looks professional and it doesn't have advertisements or anything.
