The correct response is: Local rulers maintained their local rule but had to provide tribute.
The Aztecs used a system of local rulers, often referred to as "tlatoque," to administer their vast empire. These local leaders retained a degree of autonomy over their territories, allowing them to govern according to local customs and practices. However, they were required to pay tribute to the Aztec central authority in the form of goods, labor, and military support. This system allowed the Aztecs to maintain control over a large and diverse population while ensuring a steady flow of resources back to the capital, Tenochtitlán.
