Abstract:
This study explores the leadership of Ratu Jaintan in the Sukadana Kingdom of Landak from a
socio-economic historical perspective. Using historical methods and an interdisciplinary
approach, this research involves the analysis of historical, social, and economic factors. The
research process includes collecting historical information, interpreting facts, and presenting them
in written form. Primary data sources include manuscripts, documents, artifacts, and oral
traditions, gathered through library studies, previous research, and fieldwork. Data analysis uses
deduction, induction, and comparison techniques, with quantitative data as supporting evidence.
The findings reveal that Ratu Jaintan played a key role in shaping the social and economic life of
the Landak and Sukadana Kingdoms. She promoted free trade, facilitated international trade
relations, and regulated the exploitation of natural resources such as gold and silver, while also
fostering agriculture. These efforts ensured the kingdom's economic stability and growth,
alongside maintaining social and cultural harmony.
