Signed in 1750, this Spanish-Portuguese agreement, enabled Portugal to claim more holdings in what is now Brazil; Dzungar Khanate is captured by Qing forces in 1755, ultimately transferring Xinjiang into the hands of Han Chinese power – a legacy that continues to this day in modern-day China; A destructive earthquake and tsunami ravages the city of Lisbon in 1755, strongly influencing the studies of engineering, as well as philosophical thoughts on the Western Age of Enlightenment; Britain's victory during the Battle of Quiberon Bay signalled the rise of the British Navy's power, as it heightens its ranks of becoming the world's foremost naval power, and a dominant global entity for the next two centuries; Halley's Comet appears accurately from scientific projections for the first time in 1759; Artificial refrigeration is invented and first used in 1758 under the studies of Scottish physician and chemist William Cullen; The precipitation of the French and Indian War in 1754 proved to become one of North America's first major interstate conflicts, and one of the largest to significantly involve Native American tribes such as the Iroquois, the Cherokee, and the Mi'kmaqs; Benjamin Franklin conducts his now-iconic kite experiment in 1752, leading him to the discovery of electricity and the invention of lightning rods. rect 32 32 1076 1076 Treaty of Madrid (13 January 1750) rect 1109 32 2154 1076 Revolt of the Altishahr Khojas rect 2187 32 3231 1076 1755 Lisbon earthquake and tsunami rect 32 1109 1615 2154 Kite experiment rect 1648 1109 3231 2154 Battle of Quiberon Bay rect 32 2187 1076 3231 French and Indian War rect 1109 2187 2154 3231 William Cullen rect 2187 2187 3231 3231 Halley's Comet

The 1750s (pronounced "seventeen-fifties") was a decade of the Gregorian calendar that began on January 1, 1750, and ended on December 31, 1759. The 1750s was a pioneering decade. Waves of settlers flooded the New World (specifically the Americas) in hopes of re-establishing life away from European control, and electricity was a field of novelty that had yet to be merged with the studies of chemistry and engineering. Numerous discoveries of the 1750s forged the basis for contemporary scientific consensus. The decade saw the end of the Baroque period.
