Saudi Arabia–United States relations refers to the bilateral relations between Saudi Arabia and the United States. It is a Special Relationship, which began in 1933 when full diplomatic relations were established. Despite the differences between the two countries—an ultraconservative Islamic absolute monarchy, and a secular, constitutional republic—the two countries have been allies. Former Presidents George W. Bush and Barack Obama have close and strong relations with senior members of the Saudi Royal Family."
