Codifying the Strait: The Maritime Laws of Melaka
During the reign of Sultan Muhammad Shah in the 15th century, the Malacca Sultanate formalized the
Undang-Undang Laut Melaka (Maritime Laws of Melaka) to govern commerce moving through the 550-mile Malacca Strait. The code established legal jurisdictions for sea captains, set binding rules for crew compensation, and standardized customs duties between 3% and 6% depending on a merchant vessel's port of origin across

India,

China, and Arabia. By deploying royal patrol fleets (
orang laut) to suppress regional piracy and enforcing uniform harbor arbitration, the sultanate transformed an unpoliced nautical choke point into an orderly transshipment hub. The regulatory framework proved so effective that European powers, beginning with the

Portuguese conquest in 1511, preserved its core port tariffs to maintain merchant traffic between the Indian Ocean and the South China Sea.
Why today: Malacca's reliance on enforceable maritime law to keep narrow straits commercial illuminates

Qatari officials' public refusal this morning to accept arbitrary navigation fees and transit tariffs across the Strait of Hormuz.
