In 1973, the world witnessed significant events, including the end of the Vietnam War for the United States. The Paris Peace Accords were signed in January, leading to the withdrawal of American troops and a ceasefire between North and South Vietnam. This marked a pivotal moment in U.S. foreign policy and military involvement in Southeast Asia. Additionally, 1973 was notable for the oil crisis, which began in October when OPEC (Organization of the Petroleum Exporting Countries) proclaimed an oil embargo. This led to fuel shortages and economic challenges in many countries, highlighting the global dependence on oil and prompting discussions about energy policies.
