In 1861, Doctor Richard Gatling patented the Gatling Gun, a six-barreled weapon capable of firing a (then) phenomenal 200 rounds per minute. The Gatling gun was a hand-driven, crank-operated, multi-barrel, machine gun. The first machine gun with reliable loading, the Gatling gun had the ability to fire sustained multiple bursts.
Richard Gatling created his gun during the American Civil War, he sincerely believed that his invention would end war by making it unthinkable to use due to the horrific carnage possible by his weapons. At the least, the Gatling Gun's power would reduce the number of soldiers required to remain on the battlefield.
The 1862 version of the gatling gun had reloadable steel chambers and used percussion caps. It was prone to occasional jamming. In 1867, Gatling redesigned the Gatling gun again to use metallic cartridges - this version was bought and used by the United States Army.
World power is very charming for everybody. Everybody wants to role over the world just like victor wanted to. All these people invent the machines to be the most powerful person in the world and end up harming the world with his invention.
