North America 1890: Wounded Knee Massacre
By 1890, American Indian resistance in the western United States had been crushed and settlers and railways had closed the frontier. In this environment of despair, the apocalyptic Ghost Dance religion spread quickly among Indian communities from California to Oklahoma, alarming white authorities. When, in December, 500 US Cavalry intercepted a group of 350 Lakota, mostly Ghost Dance practitioners, in South Dakota, tensions quickly led to a one-sided battle at Wounded Knee. This massacre was the last major conflict of the Indian Wars.
7–30 Apr 1885 Panama Crisis▲
In March 1885, the Colombian government moved troops stationed in Panama to deal with rebels in Cartagena, only to have Panama erupt into revolt. To protect its interests, the United States sent ships to Panama City and Colón in early April, occupying both towns around 27 April. In response to this intervention, Chile sent the modern protected cruiser Esmeralda to Panama, where it arrived on 28 April. Alarmed by Chilean actions - it was estimated that the Esmeralda could easily defeat the local US naval forces - but considering the revolt suppressed, the US withdrew from the isthmus two days later.
