Our story and why our company is called Duke Jacob.
Duke Jacob (Jakob von Kettler) was a Baltic German Duke of the Duchy of Courland and Semigallia (1642–1682). Under his rule, the duchy reached its peak in wealth. Under Kettler's rule, the duchy traded with the Netherlands, Portugal, England, France, and other nations. He started large scale reforms of the duchy's economy, improved its agriculture, opened many manufactures and started a shipbuilding industry.
Duke Jacob is remembered as a fair ruler who gave opportunities to the local Latvian peasants and even knew the Latvian language.

Like Duke Jacob, we also strive to be fair trading partners and build long term and successful relationships with our suppliers and customers, we are  passionate about outdoor activities and traveling and will provide high quality goods and services along with outstanding customer support.

We believe we are the mirror of the historical success story of Duke Jacob!
