Vietnam officially reunited in 1976. Following a prolonged conflict marked by the Vietnam War, which ended in April 1975 with the fall of Saigon, the country was unified under communist rule. The formal declaration of reunification occurred on July 2, 1976, when the Socialist Republic of Vietnam was established. This event marked the end of decades of division between North and South Vietnam and led to significant political, social, and economic transformation in the country. The reunification process faced various challenges, including integrating the two regions and addressing the aftermath of the war.
