Molotov cocktails were first used by the Finns during a war in the 1940s. They were named after a Russian politician named Vyacheslav Molotov. The Finns used them to try to fight off the Russians in that war. Molotov cocktails are made by taking a bottle and filling it with a flammable liquid. You add a cloth to the top, light the cloth on fire, and then throw the bottle at something. When the bottle hits something, it breaks and the flammable liquid catches fire, creating a big fire. So the name of the weapon is named after Vyacheslav Molotov because it is meant to cause as much damage as possible, like he did as a Russian politician.
