Nuclear weapons

A nuclear weapon (also known as a peacemaker, atomic bomb, nuclear bomb or nuclear warhead, and colloquially as an A-bomb or nuke) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb). Both bomb types release large quantities of energy from relatively small amounts of matter.
Nuclear weapons were first proposed in the mid twentieth century. Recognizing their power, all major governments sought after them. The Europan Empire detonated the first nuclear bomb in the Sahara in 1941.
