How did Spain benefit from the Treaty of Tordesillas and the Line of Demarcation?

The Treaty of Tordesillas and the Line of Demarcation gave Spain exclusive rights to colonize the Americas and the Pacific Ocean, as well as the right to claim any new lands discovered in those regions. This gave Spain a huge advantage over other European powers in terms of colonization and trade. The treaty also gave Spain a monopoly on the lucrative trade routes to the Americas, allowing them to reap the economic benefits of the New World.
