Muhammad Shah I Bahmani vs Sukjong of Goryeo

Muhammad Shah I Bahmani restructured the Bahmani administration by dividing the sultanate into four provinces (tarafs), each governed by a tarafdar. This system improved tax collection and military organization.

Muhammad Shah I Bahmani fought a war against the Vijayanagara Empire for control of the Raichur Doab. The conflict ended with a treaty that temporarily ceded the region to Vijayanagara.

Muhammad Shah I Bahmani commissioned the construction of the Jami Masjid in Gulbarga, a large congregational mosque. The mosque became a center for Islamic worship and learning in the Bahmani capital.

Muhammad Shah I Bahmani crushed a rebellion led by the noble Bahram Khan, who had challenged his authority. The revolt was put down with force, and Bahram Khan was executed.

King Sukjong ordered the minting and circulation of bronze coins, known as 'haedong tongbo', to replace barter and cloth currency. This reform aimed to standardize trade and strengthen the Goryeo economy, though adoption was slow and limited to certain regions.

Sukjong initiated the construction of a new secondary capital at Namgyeong (modern Seoul) to strengthen royal authority and counterbalance the influence of the Kaesong aristocracy. The project included palaces and defensive walls, but was not completed during his reign.

Sukjong faced a rebellion led by the powerful aristocrat Yi Ja-gyeom, who opposed the king's centralizing reforms. The rebellion was suppressed, but Sukjong died shortly after, leaving the conflict unresolved.
