Answer
World War II was the deadliest military conflict in history. It lasted from 1939 to 1945 and involved 30 countries from every part of the globe. World War II killed around 70 million people or 4% of the world's population. Historians argue over the exact numbers, so most of the following figures are from "The Fallen of World War II." It's more than the deaths incurred for all wars since then combined.
The United Nations was founded in 1945 to prevent another conflict with the horrific consequences of World War II. A controversial organization from the start, the UN has nonetheless encouraged disarmament, promoted human rights, fought poverty, and worked to promote peace worldwide. Its pursuit of stability and global humanitarian efforts also led to the World Health Organization. WHO was formed thanks to a declaration that emerged from that first meeting of the UN, setting the control of malaria, tuberculosis, and sexually transmitted diseases as its initial priorities.
