On June 13, 1381, the Peasants' Revolt is launched in London. Over the previous several decades, the domestic economy of England had reacted to the population losses of the Bubonic Plague with higher wages and a more mobile peasant working class. Parliament resisted the change with laws designed to maintain the nobility's hold over the peasantry, and on the 13th, a peasant army led by Wat Tyler (below) stormed London. King Richard II quickly acquiesced, meeting with some of the peasant "officers" the next day and agreeing to several demands, including the abolition of serfdom. But on the same day, Tyler and others in the revolt seized the Tower of London and executed the Archbishop of Canterbury. Richard met with Tyler on the 15th and in a fit of rage, the mayor of London, who was also at the meet, killed Tyler. The revolt was put down over the next couple of weeks and Richard reversed all of his concessions. On June 13, 1967, President Lyndon Johnson nominates Thurgood Marshall, an African-American and U.S. Appeals Court Judge, to the U.S. Supreme Court. The great-grandson of slaves, Marshall had served as chief counsel to the NAACP from 1938-61, during which time he argued 32 civil rights cases before SCOTUS, winning 29, most notably 1954's Brown vs Board of Education. The Senate approved the nomination on August 30 and 2 days later, Chief Justice Earl Warren swore in Marshall, making him America's first black Supreme Court Justice. On June 13, 1983, Pioneer 10 departs our solar system. Launched March 2, 1972, Pioneer 10 had navigated the asteroid belt and sent back to Earth the first detailed photographs of Jupiter before leaving the system. NASA officially ended the Pioneer 10 Project March 31, 1997, with the probe some 6 billion miles from Earth. Pioneer 10's exterior includes a 6"x 9" plaque with drawings of a man and woman, a star map indicating the location of our Sun, and another map showing the probe's flight path, on the chance it encounters an alien intelligence. It is estimated the probe will reach the star Ross 246 in the constellation Taurus in the year 34,600 A.D.
