The Mexica were the last group of the Chichimecs to arrive in the Valley of Mexico.

Early History

• Their departure from the north was around 1111 CE. They arrived in the Valley of Mexico around 1218.
• They called themselves Mexica, not "Aztec."
• Initially, they were a small community composed of groups called calpulli.
• Population growth led to the adoption of chinampas (garden beds) for growing maize, beans, potatoes, tomatoes, and other products.
• Fishing and hunting supplemented their agriculture.
• Their advanced agriculture and military strength enabled them to build a successful state and later, an empire.

The Triple Alliance and Tenochtitlan

• Many years after founding their city, Tenochtitlan, the Mexica formed an alliance with Texcoco and Tlacopan.

1. Insurance Agents

An insurance agent legally represents the insurance company (principal) and acts on its behalf. Their authority stems from express, implied, and apparent authority.

2. Insurance Brokers

A broker legally represents the insured. They don't have the authority to bind the insurer but can solicit and accept insurance applications, placing coverage with a suitable insurer. Brokers receive commissions from insurers where the business is placed.

3. Exclusive Agency System

In this system, an agent represents only one insurer or a group of insurers under common ownership. Agents may be contractually restricted from representing other insurers. They don't own policy expirations or renewal rights; the agency does. Renewal commissions are...
