Selected Events
Mayflower Departs England for the New World
In the early seventeenth century, religious Separatists in England faced ongoing persecution for refusing to conform to the Church of England. Seeking a place to worship freely, a group obtained a land patent from the Virginia Company and secured the ship Mayflower for passage across the Atlantic. On September 16, 1620, the vessel sailed from Plymouth, England, carrying 102 passengers and a crew of about thirty. The journey proved difficult, marked by storms, illness, and cramped conditions aboard the small ship. After more than two months at sea, the Mayflower reached Cape Cod in November, where the passengers eventually established the Plymouth Colony following the signing of the Mayflower Compact.
Why it matters: The voyage initiated sustained English settlement in North America and produced the Mayflower Compact, an early agreement for self-governance among the colonists. It became a foundational symbol in American history, influencing ideas of religious liberty and representative institutions that shaped later colonial and national development.
Hidalgo Issues Grito de Dolores to Start Mexican Independence
Spanish colonial rule in New Spain had created deep inequalities, with indigenous and mestizo populations facing heavy taxation and limited rights while peninsular Spaniards held power. Parish priest Miguel Hidalgo y Costilla, influenced by Enlightenment thought and local grievances, organized a conspiracy among creoles and others in the Dolores region. On September 16, 1810, Hidalgo rang his church bell to gather the people and delivered the Grito de Dolores, a call for independence from Spain, racial equality, and land redistribution. The proclamation ignited widespread rebellion across central Mexico. Although Hidalgo was captured and executed in 1811, the uprising he launched continued under other leaders until Mexican independence was achieved in 1821.
Why it matters: The Grito de Dolores launched the Mexican War of Independence and established September 16 as Mexico’s national Independence Day, celebrated annually with the presidential reenactment of the cry. It inspired similar independence movements across Latin America and embedded themes of social justice and anti-colonialism in Mexican national identity.
William Durant Incorporates General Motors
By the early twentieth century, the American automobile industry was expanding rapidly, with dozens of manufacturers competing for market share in a new technology-driven sector. William C. Durant had already turned the Buick Motor Company into a leading producer through aggressive marketing and production improvements. On September 16, 1908, Durant incorporated the General Motors Company in New Jersey, initially using $2,000 of his own funds to consolidate Buick with other firms. The new corporation quickly acquired additional manufacturers such as Olds and Cadillac. This structure allowed shared resources, parts standardization, and broader market reach in the nascent auto industry.
Why it matters: General Motors grew into one of the largest industrial corporations in the world, pioneering divisional management and mass-production techniques that defined twentieth-century American manufacturing. Its success and later challenges shaped labor relations, urban development, and global automotive competition for generations.
Bomb Detonates on Wall Street During Lunch Hour
The years after World War I brought labor strikes, anarchist bombings, and the First Red Scare to the United States, heightening tensions around radical political movements. On September 16, 1920, a horse-drawn wagon carrying approximately 100 pounds of explosives and metal fragments exploded at noon in front of the J.P. Morgan & Co. building on Wall Street. The blast killed 38 people, mostly clerical workers and messengers, and injured more than 300 others. Investigators attributed the attack to anarchist groups, though no perpetrators were ever convicted. The bombing remains one of the deadliest terrorist incidents in U.S. history prior to the twenty-first century.
Why it matters: The explosion prompted immediate increases in security around financial institutions and fueled expanded federal investigations into radical organizations during the Red Scare. It underscored the vulnerability of economic centers to domestic terrorism and contributed to long-term shifts in immigration policy and law enforcement priorities.
Papua New Guinea Achieves Independence from Australia
Papua New Guinea had been administered by Australia as separate territories for much of the twentieth century, with the two regions united after World War II. Self-government was granted in December 1973 under Chief Minister Michael Somare. The Papua New Guinea Independence Act, passed by the Australian Parliament, set September 16, 1975, as the date of full sovereignty. On that day, formal independence ceremonies took place in Port Moresby, with Prince Charles representing the British Crown and Australian officials in attendance. Somare became the country’s first prime minister in a peaceful transition that avoided the violence seen in many other decolonization processes.
Why it matters: The independence created a new sovereign state in Oceania that joined the Commonwealth of Nations and later became a member of the United Nations. It completed the withdrawal of Australian colonial administration from the region and established the institutional framework for Papua New Guinea’s ongoing political and economic development.
