play the role of a Mexican government official who believes the boundary should be the Nueces River.
When writing your speech keep the following things in mind:
Effective map analysis involves understanding what you are looking at. One effective way to do this is to locate key features (cities, rivers, mountain ranges, etc.) to better understand what the maps are telling you. For example: since the war between the US and Mexico started over a dispute between the southern boundary of Texas, you’ll need to locate the two rivers in question—the Nueces River and the Rio Grand River (also referred to as Rio del Norte or Rio Bravo)—and trace their extent to see how establishing one or the other as the international boundary would affect the size of the territory claimed by each country.
When giving your speech, be sure to make specific references to the map images you used on your slides.
When determining the points you want to make in your speech, consider things like:What advantages was your character’s side trying to achieve by claiming that boundary?
What historical claims were used to justify one boundary versus the other?
How do land claims of Native Americans factor into this debate?
If your side wins the dispute, what does your country plan to do with that territory?
