The Ottoman Empire’s recruitment of soldiers and bureaucrats through the system depicted in the image is most similar to which broader method that rulers used to strengthen their empires in the period 1450–1750?

The collection of tribute.

Explanation:

The system of taking boys into the military ranks of the Ottoman Empire is known as Devshirma. These young men were recruited and trained as the most elite Ottoman soldiers known as the Janissaries. This system is similar to taking tribute, and sometimes when the rulers of a particular country were unable to pay tribute, the Ottomans would take boys from them to serve the sultan for the rest of their lives.
