Question 5118 • GA-GSE World History A
Answer:
Since our last ambassador was here, Islam has spread far beyond the Arabian Peninsula, reaching across the region, into Africa, and into Southern Europe. Muslims have divided into Sunni and Shi'a communities over who should succeed the prophet Muhammad. The Muslim world has also made important advances in medicine and science, including al-Khwarizmi's work on algebra. Art and architecture have flourished as well, with grand mosques built in cities throughout the empire.
