1863 – Cambodia becomes a French protectorate
On August 11, 1863, Cambodia officially became a French protectorate following the signing of a treaty between King Norodom of Cambodia and representatives of the French government.
This agreement was part of France’s broader colonial ambitions in Southeast Asia, aimed at expanding its influence in the region.
The treaty placed Cambodia under French protection, ostensibly to shield it from the encroachments of neighboring powers such as Siam (Thailand) and Vietnam. Under the terms of the protectorate, the French assumed control of Cambodia’s foreign affairs and military defense, while the Cambodian monarchy retained authority over internal matters.
This marked the beginning of nearly a century of French colonial rule in Cambodia, which significantly influenced the country’s political, social, and economic development.
1909 – The first SOS signal is sent by the American ship Arapahoe
On August 11, 1909, maritime history was made when the American steamship SS Arapahoe became the first vessel to send out an SOS distress signal.
The Arapahoe, which was operated by the Clyde Line, encountered mechanical failure off the coast of North Carolina. The ship’s radio operator, T.D. Haubner, used the newly adopted SOS signal to call for assistance.
This event underscored the importance of standardized distress signals in maritime communication, which had been agreed upon at the International Radiotelegraphic Conference of 1906. The successful use of the SOS signal by the Arapahoe demonstrated the efficacy of this universal distress call, paving the way for its widespread adoption and ultimately improving safety at sea.

It aimed to create a more inclusive and democratic governance structure, granting extensive civil liberties, including freedom of speech, assembly, and religion. The Weimar Constitution also included progressive social policies, such as labor rights and social welfare provisions.
Despite its progressive aspirations, the Weimar Republic faced numerous challenges, including political extremism, economic instability, and societal divisions, which ultimately led to its downfall and the rise of the Nazi regime in 1933.

1942 – Actress Hedy Lamarr and composer George Antheil receive a patent for their “Secret Communication System,” an early technique for spread-spectrum communications and frequency hopping
On August 11, 1942, Hollywood actress Hedy Lamarr and avant-garde composer George Antheil were awarded a U.S. patent for their invention of a “Secret Communication System.” This technology was designed to prevent radio-controlled torpedoes from being jammed or intercepted by enemy forces.
The system used a method of frequency hopping, where the transmission frequency was continuously changed according to a specific sequence, making it difficult for enemies to detect or block the communication.
Although not immediately adopted by the military, their innovation laid the groundwork for later developments in secure wireless communications, including modern Bluetooth and Wi-Fi technology.
Lamarr and Antheil’s invention is now recognized as a significant contribution to telecommunications, showcasing their ingenuity and impact beyond their respective fields in entertainment.
1952 – King Talal of Jordan is deposed due to health reasons and is succeeded by his son Hussein
