Seoul: The U.S. military government, which took control of the southern part of the Korean Peninsula following World War II, imposed a ban on civilian passage across the inter-Korean border along the 38th parallel in 1946. This action came after Japan's surrender, ending its colonial rule over Korea from 1910 to 1945. The division led to the southern half being occupied by U.S. forces while the Soviet Union controlled the northern half.
According to Yonhap News Agency, significant events have occurred throughout Korean history on this day. In 1948, South Korea promulgated its first Constitution and declared July 17 as Constitution Day. This was shortly before Rhee Syng-man's inauguration as South Korea's first president. In 1969, a groundbreaking ceremony took place for the construction of the National Assembly building in Yeouido, Seoul.
The year 2006 saw devastating weather as torrential rains resulted in at least 19 fatalities and left 31 others missing in South Korea's central and northeastern regions. The heavy rains caused widespread power outages, affecting over 51,000 homes in Gangwon Province and parts of Seoul.
In 2012, the public broadcaster MBC's unionists ended a 170-day strike after lawmakers agreed to discuss the network's issues in parliament. Approximately 500 employees had demanded the resignation of MBC President Kim Jae-chul over allegations of biased coverage on politically sensitive topics.
Another pivotal moment came in 2015 when Samsung received shareholder approval for a merger of two key units. This strategic move was crucial for ensuring a smooth leadership transition to Lee Jae-yong, the son of the late group leader Lee Kun-hee.
Recent events include the recovery of five bodies from a flooded underground road in Cheongju in 2023, increasing the number of dead or missing due to heavy rains to 50. In 2024, a consortium led by Korea Hydro and Nuclear Power Co. was named the preferred bidder for constructing two nuclear power units in the Czech Republic. This marked South Korea's first overseas nuclear power plant agreement since their 2009 contract for the Barakah Nuclear Power Plant in the UAE.
