After instability during the late 1990s, Bahrain undertook substantial political reforms, but the Shiite majority continues to simmer over the Sunni-led government's perceived manipulation of laws and regulations to maintain its grip on power. Bahrain's stability has long been a key U.S. interest; it has hosted U.S. naval headquarters for the Gulf for nearly 60 years. In September 2004, the United States and Bahrain signed a free trade agreement (FTA).

This report discusses the current state of Bahrain, which has undergone substantial political reforms since the late 1990s, but which still suffers from tension between the Shiite majority and the Sunni-led government. This report focuses particularly on Bahrain's relationship with Iran and Bahrain's relationship with the United States.
