How did the dollar replace the pound as the new "world currency"? 14-15th century, in order to preach, rob gold and open up overseas markets, Europeans began water adventures and discovered new continents such as America. Subsequently, Dutch, Spanish and Portuguese gained great wealth based on colonial expansion, colonial plunder and slave trade, which made the British envious. In order to compete with Spain for maritime hegemony, the British navy and Spain's "Armada" launched a striking and fierce naval battle in the English Channel in August 1588. Unexpectedly, Spain's "Armada" was defeated by the Royal Navy, and Britain replaced Spain as the new maritime hegemon. Subsequently, many parts of the world became British colonies. When Britain was at its strongest, its territory was as high as 3,300 square kilometers, covering all continents. Therefore, Britain, also known as the "empire that never sets", is truly the largest country in the world.

By the 20th century, all countries in the world were basically divided up by Britain and France. After the rise of Germany, there is not much land in the world waiting for Germany to capture. To carve up global power again. 19 14 years, the Germans started the first world war, but the result was not satisfactory to the Germans. Germany is a key ally and lost to the allied forces composed of Britain, France and Russia. After winning World War I, Britain managed to maintain its position as the world hegemon, but at this time, the United States and the Soviet Union were still rising rapidly. 1939, the Germans who were unwilling to lose World War I once again provoked war and launched World War II. Many countries on the European continent, under the cold blitzkrieg attack of Germany, lost to Germany in succession. Even France, which had the "first army in Europe" at that time, only resisted for 42 days before surrendering to Germany. After the fall of the European continent, Britain, isolated overseas, persisted in resisting and refused to surrender.

After the outbreak of World War II, Americans adhered to the policy of "isolationism" and were unwilling to participate in the Eurasian confrontation. The United States took the opportunity to sell goods to other countries and made a fortune in the war. At first, Britain used RMB to buy materials from the United States, but soon, Americans worried that Britain would print a lot of money to win the war, making its RMB a waste paper that could not be exchanged for gold, so Britain was required to buy materials from itself with gold. The British are in urgent need of materials to resist Germany, so they can only accept American regulations. At the same time, other countries also want to use gold to buy materials from the United States, which has caused gold reserves from all over the world to flow into the United States.

194 1 year, after Japan attacked Pearl Harbor in the United States, Americans were involved in World War II, but the war of resistance of Britain, the Soviet Union and other countries could not be separated from American material supply. With the support of the United States, countries defeated the invaders and won World War II, while the United States made a fortune by selling materials and became the biggest winner of World War II. After World War II, Britain suffered heavy losses. At the same time, with the intervention of the United States and the Soviet Union, Britain's colonies in various countries in the world were divided one after another, which greatly weakened Britain and inevitably went into decline. The United States has replaced Britain as the new number one power in the world. At this time, Americans want to create a new world order with themselves as the key.

First, the President of the United States proposed to establish the United Nations with the United States and the Soviet Union as the key to replace the international alliance with Britain and France as the key. Secondly, the United States hopes that its own currency, the US dollar, will replace the British currency and become the new "world currency". During World War II, Britain used its own gold to buy American goods. It doesn't have enough gold to maintain the system of exchanging pounds for gold. During World War II, the United States allowed countries to buy materials from themselves with gold, making the post-war United States have 73.4% of the world's gold reserves. At this time, the United States is greedy and wants to replace Britain and turn its own currency, the US dollar, into a "world currency".

1944 In July, the United States invited 43 countries to hold a United Nations monetary and financial conference in Bretton Woods, New Hampshire, to discuss the international monetary system after World War II. After three weeks of intense discussions, the participating countries finally established an international monetary system centered on the US dollar, namely the Bretton Woods system, according to the final resolution of the United Nations Monetary and Financial Conference based on the White Plan and its two annexes, the International Monetary Fund Agreement and the International Bank for Reconstruction and Development Agreement. At this point, the dollar's "world currency" status has been determined. The basic principle of the Bretton Woods system is the gold exchange standard based on the dollar and gold, also known as the dollar-gold standard. Dollars and gold become equivalents, and the United States promises to issue dollars and exchange them for gold at the official price ($35 an ounce of gold). Countries can exchange dollars for gold from the United States indefinitely, which makes countries accept the status of the dollar as a "world currency". The dollar has also become the means of payment for international settlement and the key reserve currency of various countries.
