Book excerpt: The complex, often uneasy, relationship between Transjordanians and Palestinians has profoundly influenced not only Jordan but also the entire Middle East peace process. At different times, Jordan's Hashemite royalty has sought to accommodate, embrace, exclude, or cooperate with the Palestinians and the PLO, and the impact of these efforts has been felt throughout the region. Today, Jordan has signed a peace treaty with Israel, and Palestinians account for over half of the Jordanian population--yet the dynamic relationship between the regime and its Transjordanian and Palestinians citizens still arouses powerful sentiments at home and can send shock waves through the West Bank and Israel. Abu-Odeh explores this relationship from its origins in the 1920s to the very latest attempts to cope with competing national identities and to sustain a peace process.
