The Tlaxcalan leaders joined the Spanish conquistadors. What this suggests about the relationship between the Tlaxcalans and the Aztecs was that teh Tlaxcalans were enemies of teh Aztecs.
And this is correct because the Aztecs were great warriors that wage war and took prisoners. The Great Aztec Empire was a dominant one, and force other Mesoamerican Indian tribes to pay tribute. So we can say that those other small tribes or less powerful tribes had to pay tribute if they wanted to be on peaceful terms with the Aztecs.
That is why the Tlaxcalans and other tribes such as teh Chilollans decide to join forces with Hernan Cortés and teh Spanish conquerors. Together, they showed strong opposition to the Aztecas. And that was a good advantage, considered that the Spanish conquerors had horses, spades, blades, and fire weapons that impressed the Native Indians.
A deal to buy California and settle the Texas boundary line--Slidell worked as an ambassador to Mexico to offer $25 million for California and agreement to set the boundary line of Texas at the Rio Grande.
Slidell brought this deal to Mexico partly because Texas was a free independent state that wanted to be annexed by the US but had not settled their southern border. The US wanted the boundary settled before annexing Texas. Also the wanted the California region to expand land holdings. Mexico rejected the offer.
