Which was a goal of the muslim brotherhood in post world war 1 egypt

The Muslim Brotherhood wanted complete Islamic rule of Egypt.

The Muslim Brotherhood was founded in 1928 (a decade after the end of World War I).  Hassan al-Banna, an Egyptian schoolteacher, founded the movement with the goal of implementing traditional Islamic Sharia law for all aspects of life in Egypt.

Still today that remains a goal of the Muslim Brotherhood in Egypt. As one of their leaders, Khairat al-Shater, stated in a speech in 2011, the Muslim Brotherhood is "a means to Islamize life in its entirety and institute religion."
