who was the leader of the aztec/ mexica people in 1427,

and what significant alliance did he negotiate?

a. moctezuma ||; the aztec mayan alliance
b. itscoatl; the triple alliance
c. cortes; the spanish aztec pact
d. tlacpoan; the mesoamerican coalition

b. Itzcoatl; the Triple Alliance

The answer is b. Itscoatl; the Triple Alliance.

In 1427, Itscoatl became the leader of the Aztec/Mexica people. He played a significant role in negotiating the Triple Alliance, also known as the Aztec Empire. This alliance was formed between the Aztecs, Texcocans, and the Tlacopans, who were three major city-states in Mesoamerica. The purpose of this alliance was to consolidate their power and dominate the surrounding regions. This alliance eventually led to the expansion of the Aztec Empire and its dominance over much of central Mexico.

To determine the answer to this question, you can use a combination of historical knowledge and research methods. Here is how you can approach finding the answer:

Step 1: Start by understanding the context and time period. The year mentioned in the question, 1427, is during the pre-Columbian era and specifically refers to the Aztec or Mexica people.

Step 2: Identify the potential leaders mentioned in the options: Moctezuma I, Itzcoatl, Cortes, and Tlacaelel.

Step 3: Research and verify the significant alliances formed during that time. In this case, you are looking for an alliance negotiated by the leader.

Step 4: Assess the options based on the research. Compare the leaders' names with the alliances formed to find the correct answer.

Now, let's evaluate the options based on this approach:

a. Moctezuma I: The option mentions the "Aztec-Mayan alliance." However, historical records do not indicate any extensive alliance between the Aztecs and Maya during this period. Additionally, Moctezuma I ruled from 1440-1469, which does not align with the given year of 1427. Therefore, this option can be eliminated.

b. Itzcoatl: Itzcoatl was a significant ruler of the Aztec Empire from 1427-1440, which aligns with the given year. The option mentions the "Triple Alliance." This is the correct answer. The Triple Alliance, also known as the Aztec Empire, was a military and political alliance between the city-states of Tenochtitlan, Texcoco, and Tlacopan, formed around 1427.

c. Cortes: Hernan Cortes was the Spanish conquistador who arrived in Mexico in 1519, almost a century later than the mentioned year of 1427. Therefore, this option is inaccurate and can be eliminated.

d. Tlacaelel: Tlacaelel was an important figure in Aztec history, but there is no historical record indicating his leadership or role in forming a "Mesoamerican Coalition." Therefore, this option can be eliminated.

Based on the evaluation, the correct answer is b. Itzcoatl; the Triple Alliance.
