=== April&ndash;June ===
* [[April 4]] &ndash; At [[Fort Tombecbe]], near what is now the town of [[Epes, Alabama]], representatives of the British Empire and of the [[Choctaw]] Indian tribe in [[Mississippi]] sign a peace treaty in the wake of French cession of claims to the British.  A boundary is fixed between land to be occupied by the Choctaws and for lands which British settlers can use; in addition, the British agree to provide a police official and a gunsmith at Fort Tombecbe for the Choctaws to use for trespassing complaints and for weapons repairs.  By 1775, however, the Choctaws are outnumbered in Mississippi.<ref>"Mississippi", by Kathrin Dodds, in ''Native America: A State-by-State Historical Encyclopedia'', ed. by Daniel S.

* [[May 26]] &ndash; During a stroll in the park "on a fine Sabbath afternoon" at [[Glasgow Green]], Scottish engineer [[James Watt]] receives the inspiration that provides the breakthrough in his development of the [[steam engine]]; he recounts later that "The idea came into my mind, that as steam was an elastic body it would rush into a vacuum, and if a communication was made between the cylinder and an exhausted vessel, it would rush into it, and might be there condensed without cooling the cylinder... I had not walked further than the Golf-house when the whole thing was arranged in my mind."<ref>H. W.
