Aqa history coursework

My question for history coursework is "In the context of the USA between the 1865 and 1968, to what extent was Martin Luther King the most significant individual in advancing African American Civil Rights?".

Assuming this is the same as OCR then you need to do two things. The first is footnotes (which is where you put the numbers next to the quotes): if you're using MS Word, click at the end of every quote, go to Insert > Reference > Footnote and voila, it puts them at the bottom of the page for you.

I'm stuck on how much we have to write about the academic historians (do we need to know their education, political beliefs, popularity, etc?), how often we should reference them and how many primary sources to include? So far, I have 10 primary sources that I feel are relevant, but surely that's too many for a 4,500 essay max?

Thanks! But in the footnotes can you ONLY put idk ‘Ross Charles, ‘The Wars of the Roses’, pp. 208-209’ (random example) and put the small number to show where you’ve referenced it in your essay, or can you elaborate on his view? Or elaborate on the events?
