Khoury is remembered for his part in drawing up the National Pact, an agreement between Lebanon's Christian and Muslim leaders that forms the basis of the country's constitutional structure today although it was not codified in the Constitution of Lebanon until the Taif Agreement of 1989. Christians accepted Lebanon's affiliation with the Arab League and agreed not to seek French protection, and Muslims agreed to accept the Lebanese state in its present boundaries and promised not to seek unification with neighbouring Syria. The Pact also distributed seats in the National Assembly in a ratio of six Christians to five Muslims, based on the 1932 census, shich has since been modified to represent followers of both religions equally. Most significantly, the three main constitutional offices (President, Prime Minister, and National Assembly Speaker) were respectively assigned to a Maronite Christian, Sunni Muslim, and Shi'a Muslim, Lebanon's three largest confessions, respectively.
