CAIRO — Egypt’s first freely elected president, Mohammed Morsi, appeared in court on Monday on charges of inciting murder during December clashes at the presidential palace in Cairo. The trial is part of a wide-scale crackdown on his Muslim Brotherhood.

Here is a look at some of key history of the Muslim Brotherhood group:

• The Muslim Brotherhood group was founded in 1928 by a school teacher-turned-Islamic ideologue Hassan al-Banna in the Suez Canal city of Ismailia. He advocated spreading Islam by from raising up a “Muslim individual, then a Muslim family, then a Muslim society” based on Islamic teachings to pave the way for the establishment of a worldwide Islamic state that knows no borders.

• Its motto is “Islam is the solution.”

• The Brotherhood has a strong hierarchical structure, starting with the top leader -- called the “general guide,” whom members vow to “hear and obey”-- down through regional administrators to the base of small “families” made up of small numbers of members. The General Guidance Bureau serves as its main executive body, and a body known as the Shura Council serves as a form of general assembly.

• It also runs a large network of charities, hospitals and social services that help build its support. Businesses owned by Brotherhood members help finance the movement.
