All in all, the concept of Saxon appeared early than America, it was not until they take advantage and spread this idea in order to serve their own interest, both finacial and ideology wise.

Then, when the time comes to 14th century, although some of the people like Battuta hold the idea that civilization in sub-Saharan Africa isn't worse than western civilization. The majority of western people still rebuff this idea for maintaining the slave trade. On the contrary, people like Zurara portrayed the slave trade as providing freedom in Africa, additionally, his idea and article created Blackness. Because of the interest of slave traders and lack of understanding, the concept of race was gradually formed. By the late 1600s, with the scientific revolution, scientists started to sort people into categories, and eventually, the concept of three races appeared.

But, from the podcast, although most of the founding fathers hold the idea of "All Men Equal", the law related with race and some details mentioned in the podcast already showed a society full filled with contradiction, unequality, and bloody history. During that time, majority of people holds the race idea which is the supority of Anglo-Saxons.

Thus, we could know that there's still lots of problems appeared in early America and it is not a so-called land of freedom or eqality.

Thus, we know that only the ones who are in power or certain groups of people are able to get their right to freedom, but their "free right" and self-interest come from depriving others of their freedom even after the publish of Delcaration of Indipendence.

Thomas Jefferson, one of the founding fathers mentioned in the podcast, also wrote, "All men are created equal". But on another day, he wrote the idea that African Americans are inferior, etc. The interesting thing is what happened after his words were published. Although back in that time, most of the people have the same idea but he still recieved letters who against his idea. He replied and approbate these idea. From the study of researchers, we know that personally, Jefferson seems to approve the anti-race idea, but at the same time, his self-interest is deeply bound with slavery, and he also approves the idea of the superiority of White people.

From contradiction happened on Jefferson, we can took a glance of the current situation of equality of America.

From the laws they published and what's going on with these slaves, we could merely guess how some groups of Indians were being treated at that time. As well as inside the podcast, the announcer mentioned Indian genocide, also telling some of the Indian's disappearance implicitly.

During that time, most people didn't categorize based on heredity but climate. This theory is called "Climate Theory". They coming up temperate region of the Mediterranean has produced the most superior peoples, while the extreme cold or extreme hot northern or southern climates leading to these inferior peoples. Which gave them a reason to eslave people.

But, people like Alcidamas challenged these notions with reasonable evidence. He wrote, “God has left all men free; nature has made no man a slave.” But since promoting these ideas made it difficult for slave traders, his idea was shouted down as lies.

In a nut shell, they surely categorize people based on their culture or region. But didn't base on genetic factors.

From the recording by Zurara, written in 1453, we can see that first-time settlers from Europe categorized and came up with racial ideas so that they could enslave a group of people with a perfect reason. They invented the concept of black.

By the 1500s, his ideas in the book had strongly influenced other countries in Europe.

Then, the thought of race came to America by the British which evolved to the race idea we know today. Thus, race is not the reason for slavery, but slavery is the reason for race.

Then, from Thomas Jefferson, he holds an idea that America is a Saxon country, and he wants racial purity. Also, from John, he mentioned that the idea resulted from oppression, so the definition of white in that special time was one who holds basic rights, not seriously based on color or blood relation.

Thus, in summary, we know that Emerson opposed slavery not because he cared about people who were enslaved but because of his idea about the Saxon race being kind and intelligent.
