Egyptian Jews constitute both one of the oldest and youngest Jewish communities in the world. The historic core of the indigenous community consisted mainly of Arabic-speaking Rabbanites and Karaites. After their expulsion from Spain, more Sephardi and Karaite Jews began to emigrate to Egypt and their numbers increased significantly with the growth of trading prospects after the opening of the Suez Canal in 1869. As a result, Jews from all over the territories of the Ottoman Empire as well as Italy and Greece started to settle in the main cities of Egypt, where they thrived. The Ashkenazi community, mainly confined to Cairo's Darb al-Barabira quarter, began to arrive in the aftermath of the waves of pogroms that hit Europe in the latter part of the 19th century.
