The Hijra, Little Rock and the Nuclear-Test-Ban Treaty: September 24 Across the Centuries

Seven moments connect the formation of the early Muslim community, judicial power, powered flight, postwar industry, school desegregation, African independence and the effort to prohibit nuclear tests.

Chronology note: No securely attested September 24 event was identified for ancient Egypt, Mesopotamia, the Bronze Age, classical Greece or Rome. September 24, 622 is a traditional Gregorian conversion for Muhammad’s arrival at Quba near Medina; early Islamic sources use a lunar calendar, and modern conversions vary. It is included with that uncertainty made explicit.

Muhammad reaches the oasis of Medina during the Hijra

Islamic tradition records Muhammad’s migration from Mecca to the oasis later known as Medina in 622, after growing opposition in Mecca and invitations from supporters in Yathrib. A frequently cited modern conversion places his arrival at Quba on September 24, though reconstructions also give nearby dates. The Hijra was not merely a flight from persecution: in Medina, Muhammad led a political and religious community whose agreements, alliances and conflicts shaped the early Islamic state. The Muslim calendar later counted its years from the Hijra, though its first month does not correspond to the arrival day.

1789 · United States

The Judiciary Act creates the federal court system

President George Washington signed the Judiciary Act on September 24, 1789. The Constitution had established a Supreme Court but left much of the national judiciary for Congress to design. The act created district and circuit courts, set the first Supreme Court at six justices and established the office of attorney general. Later laws repeatedly changed that structure, but the act turned a brief constitutional framework into an operating judicial system and helped define how federal law would be enforced across the states.

1852 · France

Henri Giffard pilots a steam-powered airship

French engineer Henri Giffard flew a steam-powered, steerable airship from Paris to Trappes on September 24, 1852. Balloons had carried people for decades, but they largely moved with the wind. Giffard’s elongated craft combined a lightweight steam engine, propeller and rudder, demonstrating controlled powered flight despite being unable to return against strong winds. It was not an airplane and not the first human flight; it was a crucial step toward practical dirigibles and powered navigation through the air.

1948 · Japan

Honda Motor Company is incorporated

Soichiro Honda and Takeo Fujisawa built a postwar manufacturer around small engines and inexpensive transportation. Honda Motor Company was incorporated on September 24, 1948, initially producing motorized bicycles and motorcycles before expanding into automobiles and global manufacturing. Its rise reflected Japan’s industrial recovery, engineering culture and export growth. The company’s later success also helped change international perceptions of Japanese manufacturing from low-cost production to reliability and technical innovation.

1957 · Little Rock, Arkansas

Eisenhower federalizes the National Guard and sends Army troops

President Dwight Eisenhower issued Executive Order 10730 on September 24, 1957, placing the Arkansas National Guard under federal authority and ordering federal forces to enforce court-ordered desegregation at Central High School. Governor Orval Faubus had used the Guard to block nine Black students from entering. Soldiers of the 101st Airborne Division escorted the students the next day. Federal intervention secured entry, but it did not end harassment or resistance; it demonstrated that constitutional rulings required executive enforcement when state power openly defied them.

1973 · Guinea-Bissau

The PAIGC declares independence from Portugal

The African Party for the Independence of Guinea and Cape Verde proclaimed the Republic of Guinea-Bissau on September 24, 1973, in territory it controlled after years of anticolonial war. Many states recognized the new republic, and it entered the United Nations that November. Portugal did not formally recognize independence until September 1974, after the Carnation Revolution ended the dictatorship in Lisbon. The declaration therefore marked both a real transfer of authority on the ground and a sovereignty claim still contested by the colonial power.

1996 · United Nations

The Comprehensive Nuclear-Test-Ban Treaty opens for signature

The Comprehensive Nuclear-Test-Ban Treaty opened for signature at the United Nations on September 24, 1996. It prohibits nuclear explosions for military or civilian purposes and created an international monitoring system using seismic, hydroacoustic, infrasound and radionuclide stations. The treaty has established a powerful global norm and verification network, but it has not formally entered into force because several states specifically named in its annex have not ratified it. The distinction matters: widespread observance is not the same as full legal activation.

Across the centuries

Institutions turn declarations into durable power

The Hijra created a community, the Judiciary Act built courts, Giffard joined propulsion to navigation, and Honda organized engineering for mass production. At Little Rock, a court order became enforceable only through federal action; Guinea-Bissau’s declaration gained force through territorial control and recognition; the test-ban treaty relies on both signatures and a worldwide monitoring system. Each event shows that lasting change needs institutions capable of carrying an idea into practice.
