Jacob Kettler

Jacob Kettler was a Baltic German Duke of the Duchy of Courland and Semigallia (1642–1682). Under his rule, Courland and Semigallia became more independent of its Polish suzerain, reached its peak in wealth, and even engaged in its own overseas colonization, making it one of the smallest, but fastest growing states in the world at that time.
