The groundwork for Nato and the United Nations

NATO, or the North Atlantic Treaty Organization, is a military coalition that was initially formed to oppose the Soviet Union and is currently doing the same with Russia. Additionally, the United Nations was created as a venue for diplomatic discussions among its member states.

Only 36% of Wellington's army was genuinely British; the remaining men were from various German duchies as well as the Netherlands and Belgium. Additionally, Wellington's men collaborated with the 50,000-strong Prussian army (Prussia eventually became a part of Germany) to beat the French, which is why Lord Bramall, the previous head of the British military, referred to Waterloo as "the first Nato operation." NATO and the United Nations have their roots in the Battle of Waterloo. It was considered one of the best significance of the battle of Waterloo and the first NATO operation as the Prussian army worked there to defeat the French with the forces of Wellington.

In the Waterloo Passage of Lord Byron's poem Childe Harold's Pilgrimage, the phrase "united nations" appears. This was used to describe the allied war objectives after Pearl Harbor by Winston Churchill, and the phrase was later used to refer to the renowned international organization.
