When Queen Elizabeth II came into power, Britain still ruled over more than 70 overseas territories. In fact, colonization was still very much a thing during the 20th century and beyond as Britain stayed hungry for power and control. Take the case of Barbados, which wasn't able to remove Queen Elizabeth II as its ceremonial head of state until 2021.

It was mainly during Queen Elizabeth II's reign that the British military notoriously engaged in mass murder and forced civilians into concentration camps. As Uju Anya, a professor of applied linguistics, wrote on Twitter, some of her ancestors lost their lives as Britain continued to dominate overseas territories.

For example, during the Mau Mau Rebellion in the '50s, the Kenya Human Rights Commission (per BBC) estimated that 90,000 Kenyans were executed, tortured, or maimed, and 160,000 were "detained in appalling conditions." Meanwhile, only 32 English settlers were thought to have been killed.

While Queen Elizabeth II wasn't directly responsible for these mass killings, many people argue that she could have done something to help, even though she was believed to have had very little power in the British government.
