With nearly 85 million people, Egypt is Africa's most populated country. With little arable land and dependence on the Nile River, Egypt has dealt with economic challenges and limited resources throughout history. It is a republic with a developing economy, and the official language is Modern Standard Arabic. English is the most commonly spoken foreign language. The relationship between the U.S. and Egypt has been strained in recent years, with President Barack Obama referring to the relationship in recent months as a "work in progress."
