With the arrival of Islam in the 600s the local people accepted the religion and eventually the Arabs comprised the region's majority. The people's lives, then and now, are dictated by the Islamic faith as they follow numerous dietary restrictions, social demands, and their greatest architectural achievements are in the form of mosques.
From the 600s on, the people of modern day Jordan had few differences from their neighboring people. During much of this time the people fell under foreign rulers and these outside influences changed the people as the Middle East became more uniform. Lebanese and Turkish foods became the dietary norm as the region fell under Syrian and Turkish rulers among others. For most of the next 1500s years the people in Jordan fell on the periphery of kingdoms so no substantial introductions ever arrived as the country continued on its path.
After World War I ended in the 1910s, the British took over Jordan and the region's culture began to substantially change. Technology, communication, infrastructure, and more were introduced as the region modernized. The region also gained greater freedom from neighboring countries such as Syria. This led to greater self-identity as the people changed their dress and mentality in slight ways to differentiate themselves from their neighbors, only at this point first calling themselves Jordanian.
After World War II ended in the 1940s, the Jordanian's identity was quite strong, just as they gained independence and Israel was being formed. Israel created a perfect antithesis to Jordanian identity and many people used these differences to magnify Jordanian culture, while warring with their newly formed neighbor. Despite the initial battles, the Jordanian people later turned to peace and diplomacy as they began to view themselves as a more liberal variety of Islam, while opening their doors to refugees from Israel. Today the Jordanians get along with the Israelis, Syrians, Saudis, and Iranians along with many more as the country consists of Jordanians, Palestinians, and many other people.
These relationships and modernization have also slightly shaped Jordan as the country today mixes conservative Islamic values with technology, balancing conservative diets, clothing, and beliefs with a vibrant night life in cafes and western-styled clothing.
