King Felipe II's severe financial troubles directly forced the Spanish Empire to adopt an aggressive, hyper-focused resource mining strategy that prioritized immediate high-yield assets over long-term industrial development. Felipe II inherited a massive state debt from his father, Charles V, and proceeded to declare sovereign bankruptcy four separate times (in 1557, 1575, 1576, and 1596) due to the astronomical costs of his global wars. To keep his empire afloat, his administration treated mining not as a tool for economic growth, but as an emergency cash register.
