Why was Anatolia attractive to Assyrian merchants during the Middle Bronze Age?

During the Middle Bronze Age, Anatolia was highly attractive to Assyrian merchants primarily due to the region's significant mineral wealth.1

To facilitate the extraction and trade of these resources, Assyrian merchants established a network of trading colonies known as a karum, with the principal colony located at Kanesh (modern-day Kültepe). These colonies functioned similarly to a chamber of commerce, providing the necessary infrastructure to fix prices, manage debts, and organize the transport of goods back to Ashur.1

The merchants operated through formal agreements with local Anatolian rulers, to whom they paid taxes in exchange for the right to establish themselves in the suburbs of various cities. This period was marked by a cooperative relationship, as evidenced by the Assyrian archives found at Kanesh, which indicate that the merchants lived on good terms with their neighbors and frequently intermarried with the local population.1
