King Gongmin vs Raja Raja Chola I

Gongmin launched military campaigns to reclaim northern territories that had been ceded to the Yuan dynasty. Goryeo forces recaptured the Ssangseong and Dongnyeong regions, restoring the kingdom's traditional borders.

King Gongmin expelled Mongol officials and military personnel from Goryeo, ending the Yuan dynasty's direct control over the kingdom. He abolished the Mongol-style administrative offices and reasserted Goryeo's sovereignty.

Gongmin implemented a series of reforms to eliminate Mongol influence, including restoring Korean names for government offices, reviving Confucian rituals, and promoting native Korean culture. These reforms strengthened national identity.

Queen Noguk, Gongmin's Mongol wife and close advisor, died under mysterious circumstances, possibly by poisoning. Her death deeply affected Gongmin, leading to his increasing paranoia and erratic behavior in later years.

King Gongmin was assassinated by his eunuchs and close aides, possibly with the involvement of pro-Mongol factions. His death ended the reform era and led to a period of political instability in Goryeo.

Raja Raja Chola I ascended the throne of the Chola Empire, succeeding his father Parantaka II. He inherited a kingdom in the Tamil region and began a series of military campaigns that would transform the Chola state into a major power.

Raja Raja Chola I defeated the Chera king Bhaskara Ravi Varman and annexed the Chera territories in present-day Kerala. This conquest gave the Cholas control over the Malabar Coast and its spice trade.

Raja Raja Chola I conducted a comprehensive land survey and reorganized the revenue system. He standardized tax collection and recorded land holdings in inscriptions, which improved administrative efficiency and funded his military and building projects.

Raja Raja Chola I launched a naval expedition against the Srivijaya Empire in Southeast Asia, targeting the Strait of Malacca. The campaign disrupted Srivijaya's trade monopoly and established Chola influence in the region, though full conquest was not achieved.

Raja Raja Chola I commissioned the construction of the Brihadeeswarar Temple in Thanjavur, dedicated to Shiva. The temple, built with granite, features a 66-meter vimana and is a masterpiece of Dravidian architecture, later designated a UNESCO World Heritage site.
