"Jefferson hosted the United States' first iftar at the White House. It was an unintentional event, one that occurred as a result of Jefferson's scheduled meeting with an invited envoy from the Tunisian government. It was the end of the first Barbary War, and Jefferson was anxious to establish better diplomatic relations with the North African states while ensuring the security of American interests in the Mediterranean. Upon being informed of the envoy's fasting to observe the Islamic month of Ramadan, Jefferson had the mealtime at the White House changed from 3:30 in the afternoon to "precisely at sunset" in an effort to accommodate his guest. This gesture on behalf of the president was not simply a diplomatic one, but one that demonstrated Jefferson's familiarity and comfort with Islam, a faith that interested him since his time as a student at the College of William & Mary. Indeed, Jefferson's interest in the Qur'an and his own study of Arabic led to his active promotion and eventual creation of an Oriental Languages department at his alma mater. As a scholar and a diplomat, Jefferson was keenly aware and interested in the world outside of America and the importance of cultural and intellectual capital to the success of the United States."
