The Sentinelese people, residing on North Sentinel Island in the Indian Ocean, have inhabited the island for an estimated 60,000 years. Their population ranges from about 80 to 150 individuals, and they maintain a hunter-gatherer lifestyle reminiscent of the Stone Age, devoid of agricultural practices. Numerous attempts to contact this tribe from the outside world have resulted in vehement hostility. In 1771, an East India Company ship observed numerous lights on the shores of North Sentinel Island but refrained from investigating. In 1867, an Indian merchant ship was compelled to land on the island due to severe monsoons, prompting an attack by the islanders with arrows. The crew managed to defend themselves with rudimentary weapons until the Royal Navy came to their rescue. In 1880, the British revisited the island and discovered an abandoned village inland. They kidnapped six Sentinelese individuals, all of whom fell ill upon exposure to the outside world. In 1896, an escaped convict reached the island, only to be found dead with arrows and a slit throat. In 2018, an American Christian missionary ventured to the island with the intent of converting the indigenous people. Despite warning shots and attempts to communicate, he was tragically killed by arrows, and his body remains unrecovered on the island.

The last American slave ship arrived in Mobile, Alabama, in 1860, despite the illegal importation of slaves. On board were approximately 160 West African individuals who had been captured and enslaved. One of the captives, named Cudjo Lewis, was acutely aware of the potential erasure of his birth culture as he toiled in this new land. However, when he eventually gained his freedom, Lewis took action to preserve his heritage. Using the money he had earned, Cudjo Lewis purchased two acres of land and established a self-sufficient community for the survivors of the last slave ship. This community, known to outsiders as Africatown, aimed to recreate aspects of the West African home from which they had been forcibly removed. Lewis wanted to ensure that extended families could live together, conversations could be held in regional languages, and traditions that might otherwise have been lost in America could be maintained. Today, Africatown still exists as a community and continues to house the descendants of the individuals who were brought to America on the nation's last slave ship. It stands as a testament to the resilience and determination of those who fought to preserve their heritage and maintain a sense of cultural identity in the face of tremendous adversity.

Stanislav Petrov, the man who saved the world from nuclear disaster, on this day in 1983, 39 years ago today, saw the word "LAUNCH" flash across the Soviet Union's attack early warning system. His screen stated with high reliability that a total of five American intercontinental ballistic missiles (ICBMs) had been launched and were headed toward the Soviet Union. Petrov had to make a decision: should he report an incoming American strike, or should he hold off, confident that what they were seeing was a false alarm? If he reported it, Soviet nuclear doctrine called for a full nuclear retaliation. There would be no time to double-check the warning system or seek negotiations with the U.S. This occurred during the Reagan administration, which had taken a firmer stance against the Soviets compared to previous administrations. The Reagan administration was deploying Pershing I nuclear-armed missiles to West Germany and Great Britain, capable of striking the Soviet Union. Given these circumstances, Petrov had reasons to believe that Reagan's brinkmanship had escalated to an actual nuclear exchange. However, Petrov chose not to report the incoming strike. In the end, his decision proved to be correct. The system had mistaken the sun's reflection off of clouds for a missile. A 1979 report by Congress had estimated that a full-scale Soviet assault on the U.S., and an eventual counter-strike, would have resulted in over 100 million deaths. Petrov, almost single-handedly, prevented those deaths. Despite being right, Petrov was relentlessly interrogated afterward and never rewarded for his decision, according to David Hoffman of The Washington Post.
