Prior to his reign, Morocco had experienced 30 years of internecine battles, instability and turmoil. During the 33 years Sidi Muhammad ruled he transformed the politics, the economy and the society, putting development of international trade high on his agenda and restoring power to the sultanate. This served to quickly bring respect to Morocco on the international scene. Central to his pursuit of international trade was the negotiation of agreements with foreign commercial powers. He actively began seeking one with the United States well before the war with Great Britain was settled in 1783, finally got America's attention in 1784, and warmly welcomed Thomas Barclay's arrival to negotiate in 1786. The treaty signed by Barclay and the sultan, then by Jefferson and Adams, was ratified by the Confederation Congress in July 1787. It has withstood transatlantic stresses and strains for more than 232 years, making it the longest unbroken treaty relationship in United States history.

A valid U.S. passport or passport card is preferred, although a birth certificate, naturalization certificate, citizenship certificate, or another document proving U.S. nationality, together with a government-issued photo ID (such as a driver's license) are acceptable to establish identity and nationality. However, the documents required to return to the United States can be more restrictive (for example, a birth certificate and photo ID are insufficient) -- see the section below on Return entry into the U.S.

Ford released the original model in 2000 for the 2001 model year--a model jointly developed and released with Mazda of Japan--who took a lead in the engineering of the two models and sold their version as the Mazda Tribute. Although the Escape and Tribute share the same underpinnings constructed from the Ford CD2 platform (based on Mazda GF underpinnings), the only panels common to the two vehicles are the roof and floor pressings. Powertrains were supplied by Mazda with respect to the base inline-four engine, with Ford providing the optional V6. At first, the twinned models were assembled by Ford in the US for North American consumption, with Mazda in Japan supplying cars for other markets. This followed a long history of Mazda-derived Fords, starting with the Ford Courier in the 1970s. Ford also sold the first generation Escape in Europe and China as the Ford Maverick, replacing the previous Nissan-sourced model. Then in 2004, for the 2005 model year, Ford's luxury Mercury division released a rebadged version called the Mercury Mariner, sold mainly in North America. The first iteration Escape remains notable as the first SUV to offer a hybrid drivetrain option, released in 2004 for the 2005 model year to North American markets only.
