Robert Charles riots. Tuesday, July 24, 1900 Revolutionaries in China signed the document "Regulations for Peaceful Rule", written by lawyer Kai Ho, including Sun Yat-sen, as well as Yang Chu-yun and Xie Zhantai (Tse Tsan Tai), for presentation to Hong Kong Governor Henry Arthur Blake, requesting British help in reconstructing China to a parliamentary government, with an advisory body composed of foreign ambassadors. In the pre-dawn hours, Robert Charles shot and killed Captain John Day and Patrolman Peter J. Lamb of the New Orleans Police Department as they entered his home. Although the home was surrounded, Charles was able to escape. The incident would trigger the "Robert Charles riots".

Two days later, Charles was located at 1208 Saratoga Avenue and killed, but not before he shot 24 people. Thursday, July 26, 1900 The Office of the United States Postmaster General issued its Order No. 875, which provided that "the introduction of rural free delivery will not increase or otherwise modify the present rate of postage on second-class matter", increasing the delivery of magazines and newspapers to rural locations. Friday, July 27, 1900 Kaiser Wilhelm gave the infamous "Hun Speech" at Bremerhaven, Germany as he dispatched troops to fight in China. The most inflammatory line was, "Wie vor tausend Jahren die Hunnen unter ihrem König Etzel sich einen Namen gemacht, der sie noch jetzt in Überlieferung und Märchen gewaltig erscheinen läßt, so möge der Name Deutscher in China auf
