1. The four states of United States that border Mexico are Texas, New Mexico, Arizona, and California. There are multiple similarities between these four states, be it in their geography or culture. The most striking similarities are that all of these four states have a very percentage of population that has Mexican ancestry, and that the Spanish language is commonly used, but at home and officially. There are two main reasons for this. One of them is that these states were once part of Mexico, so when the United States managed to conquer them, they encountered mostly Mexicans, which did not returned to Mexico but stayed in the United States. Another reason is that they border with Mexico, so the Mexicans that migrate toward the United States mostly end up in these states, or are there for at least some time.
2. The differences between these four states can be mostly seen in their economies and their cultures. The economies of these four states are all different. Texas for example is focused on the oil reserves, as well as large scale farming and ranching, while California is mostly focused on the tertiary sectors, such as its famous movie industry. The culture too differs in all of these states, which is actually a trait of any state in the United States as all of them have something specific about them. The Texans tend to be more rough, love weapons, and are much more conservative. The Californians tend to be much more libertarian, more easy going, and love the spotlight. The New Mexicans and Arizonians are not very open, they tend to be more closed and function in their communities, while not being very willing to engage with ''outsiders''.
Answer: Most of Arabia was under Muslim control by the time Muhammad died. After his death, later caliphs unified Arabia and expanded Islamic territory across the Middle East and North Africa.
