President Richard Nixon completes the break from the gold standard by ending convertibility of the United States dollar into gold by foreign investors.

A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold foreign central banks, effectively ending the Bretton Woods system. Many states still hold substantial gold reserves.Historically, the silver standard and bimetallism have been more common than the gold standard. The shift to an international monetary system based on a gold standard reflected accident, network externalities, and path dependence. Great Britain accidentally adopted a de facto gold standard in 1717 when Sir Isaac Newton, then-master of the Royal Mint, set the exchange rate of silver to gold too low, thus causing silver coins to go out of circulation. As Great Britain became the world's leading financial and commercial power in the 19th century, other states increasingly adopted Britain's monetary system.The gold standard was largely abandoned during the Great Depression before being re-instated in a limited form as part of the post-World War II Bretton Woods system. The gold standard was abandoned due to its propensity for volatility, as well as the constraints it imposed on governments: by retaining a fixed exchange rate, governments were hamstrung in engaging in expansionary policies to, for example, reduce unemployment during economic recessions. There is a consensus among economists that a return to the gold standard would not be beneficial, and most economic historians reject the idea that the gold standard "was effective in stabilizing prices and moderating business-cycle fluctuations during the nineteenth century."

Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th president of the United States, serving from 1969 to 1974. He was a member of the Republican Party who previously served as a representative and senator from California and was the 36th vice president from 1953 to 1961. His five years in the White House saw the end of U.S. involvement in the Vietnam War, détente with the Soviet Union and China, the first manned Moon landings, and the establishment of the Environmental Protection Agency. Nixon's second term ended early, when he became the only president to resign from office, following the Watergate scandal.

Nixon was born into a poor family of Quakers in a small town in Southern California. He graduated from Duke Law School in 1937, practiced law in California, then moved with his wife Pat to Washington in 1942 to work for the federal government. After active duty in the Naval Reserve during World War II, he was elected to the House of Representatives in 1946. His work on the Alger Hiss Case established his reputation as a leading anti-Communist, which elevated him to national prominence, and in 1950, he was elected to the Senate. Nixon was the running mate of Dwight D. Eisenhower, the Republican Party's presidential nominee in the 1952 election, and served for eight years as the vice president. He ran for president in 1960, narrowly lost to John F. Kennedy, then failed again in a 1962 race for governor of California. In 1968, he made another run for the presidency and was elected, defeating Hubert Humphrey and George Wallace in a close contest.

Nixon formally ended American involvement in Vietnam combat in 1973, and with it, the military draft, that same year. His visit to China in 1972 eventually led to diplomatic relations between the two nations, and he also then concluded the Anti-Ballistic Missile Treaty with the Soviet Union. In step with his conservative beliefs, his administration incrementally transferred power from the federal government to the states. Nixon's domestic policy saw him impose wage and price controls for 90 days, enforce desegregation of Southern schools, establish the Environmental Protection Agency, and begin the War on Cancer. Additionally, his administration pushed for the Controlled Substances Act and began the War on Drugs. He also presided over the Apollo 11 Moon landing, which signaled the end of the Space Race. He was re-elected with a historic electoral landslide in 1972 when he defeated George McGovern.

In his second term, Nixon ordered an airlift to resupply Israeli losses in the Yom Kippur War, a war which led to the oil crisis at home. By late 1973, the Nixon administration's involvement in the Watergate eroded his support in Congress and the country. On August 9, 1974, facing almost certain impeachment and removal from office, Nixon resigned the presidency. Afterwards, he was issued a pardon by his successor, Gerald Ford. In his almost 20 years of retirement, Nixon wrote his memoirs and nine other books and undertook many foreign trips, rehabilitating his image into that of an elder statesman and leading expert on foreign affairs. He suffered a debilitating stroke on April 18, 1994, and died four days later at age 81. Surveys of historians and political scientists have ranked Nixon as a below-average president. Evaluations of him have proven complex, as the successes of his presidency have been contrasted with the circumstances of his departure from office.
