Seoul: Today marks significant events in Korean history, ranging from advancements in communication to diplomatic tensions. On April 6, 1887, the Joseon Dynasty, which ruled Korea from 1392 until 1910, took a pivotal step in the country's modernization by establishing a government agency dedicated to telegraph services. This move was instrumental in enhancing communication across the region during that era.

According to Yonhap News Agency, another noteworthy historical moment occurred in 1984 when the Seoul Olympic Organizing Committee unveiled Hodori, a tiger, as the official mascot for the 1988 Olympic Games. The selection of Hodori symbolized the spirit and aspirations of South Korea as it prepared to host the international sporting event in Seoul.

The year 2015 saw South Korea engaged in a diplomatic dispute with Japan over the Dokdo islets, located in the East Sea. South Korea criticized Japan for intensifying its territorial claim to Dokdo in newly published school textbooks. The foreign ministry in Seoul urged Tokyo to take meaningful steps to enhance bilateral relations. Notably, 13 out of 18 textbooks for Japanese middle schools included Japan's assertion that South Korea is wrongfully occupying the islets, a significant increase from the four textbooks that contained the claim in 2011.

In a separate event on April 6, 2018, former South Korean President Park Geun-hye was sentenced to 24 years in prison and fined 18 billion won following a large-scale corruption scandal. This verdict from the Seoul Central District Court came about a year after her arrest in March 2017, marking a dramatic fall from power. In a final ruling on January 14, 2021, the Supreme Court reduced her sentence to 20 years.
