Cairo is the cultural capital of the Arab world. Its TV and cinema productions have long shaped Arab popular culture. As a result, Egyptian Arabic is understood throughout the entire Arab world and Egyptian soap operas, sitcoms, and dramas are followed avidly from Morocco to Oman.
As the biggest city in the Middle East, Cairo is the political and economic hub of the Arab world. Since Egypt has by far the largest number of Christians of any Arab country (25 million), Egyptian Christians, and especially churches in Cairo, exercise enormous influence.
Sunni Islam’s most prestigious university, Al-Azhar University, was founded in Cairo in 970 AD. It serves as the global arbiter of Sunni Muslim theology and law. Future imams (prayer leaders in mosques) from nearly every Sunni Muslim-majority country on the planet are trained at Al-Azhar.
This ancient seat of Islamic education shapes the thinking and the devotion of hundreds of millions of Muslims. Also, the Cairo-birthed Muslim Brotherhood, which has close ties with Al-Azhar, exerts a radicalizing influence among Muslims around the world.
