A slow expansion of women's rights began under the late King Abdullah, who appointed female advisers to the Shura Council in 2013.

There were no attacks against American forces and Westerners in the country until after 1995.
After the September 11, 2001 attacks, there was continued world pressure for the Saudi government to crack down on the radical imams preaching anti-American rhetoric in Saudi mosques.
