Who is Cecil Rhodes and why are UK demonstrators protesting at his statue?

Protestors hold placards and shout slogans during during a protest called by the Rhodes Must Fall campaign calling for the removal of the statue of Cecil John Rhodes outside Oriel Cllege, at the University of Oxford on June 9, 2020.

(CNN)Hundreds of protesters in Oxford took to the streets outside the famed university's Oriel College on Tuesday, to demand the removal of a statue of Cecil Rhodes.

The long-running campaign to remove the statue has been reinvigorated after the recent Black Lives Matter protests in the US following the death of George Floyd.
Anti-racism protesters in the UK previously pulled down the statue of slave trader Edward Colston in the English port city of Bristol on Monday.
    Members of the Oxford crowd on Tuesday took a knee, put their fists in the air and kept silent for 8 minutes and 46 seconds, the amount of time Minneapolis police officer Derek Chauvin held his knee on Floyd's neck.

    Why are people protesting about statues of Cecil Rhodes? Who was he?

    Cecil Rhodes was one of the leading figures in British imperialism at the end of the 19th Century, pushing the empire to seize control over vast areas of southern Africa, first as a businessman and later as prime minister of Cape Colony in what is now South Africa.

    Why did he do that?

    Rhodes had both financial and political reasons. He co-founded the De Beers diamond company, which sought to control ever greater territory for its diamond mining. In Rhodes' lifetime, the company controlled about 90% of the world's diamond mines.
    But he also held a deep-seated belief that the British should run things because they were simply better than other people. As he famously put it: "You are an Englishman, and have subsequently drawn the greatest prize in the lottery of life." (The quote is often summarized as "to be born an Englishman is to win first prize in the lottery of life.")
