What is "mutamassirun"

The Mutamassirun (, plural, or Mutamassir in singular, literally "Egyptianized") refers to "Egyptianized" foreigners residing in Egypt, primarily during the 19th and 20th centuries.

The Mutamassirun community was first established in Egypt in the early 19th century, following the French campaign in Egypt and Syria and Muhammad Ali's seizure of power. From the early 20th century they became an important component of Egyptian society, and despite their diversity were usually viewed as a homogenous group by Egyptian nationalists.

The populations considered alien by the Nasserists (e.g. Greeks, Italians, and Jews) were expelled in the 1950s.
