It was never formally annexed to Egypt, 1964# though. 1965# 1966# The rest of Palestine was under Jordanian rule at that time, formally 1967# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 1968# the country's previous name of "the Hashemite Kingdom of the 1969# Trans-Jordan").
