The founding of PEN International in London (October 6) took place in 1921. This organization was established to support writers and promote freedom of expression worldwide. At that time, a group of writers, editors, and poets gathered in London to create an international body dedicated to defending the rights of authors and fostering literary cooperation. PEN International, as it became known, was initially founded by Catherine Amy Dawson Scott and a group of prominent writers. The organization quickly expanded, establishing branches in various countries and becoming a platform for dialogue and collaboration among writers from diverse cultures and languages. Its main goal was to support freedom of expression and to oppose censorship. In the years that followed, PEN International played a significant role in supporting imprisoned writers and defending human rights. Through conferences, public statements, and cultural activities, the organization worked to bring attention to the plight of writers at risk. The founding of this association on October 6, 1921, marked the beginning of a global movement to support literary freedom and the rights of writers. This observance was added to the Gregorian calendar because of the historical importance of establishing an international institution dedicated to supporting writers and freedom of expression, and it was designated as a significant day by literary and cultural activists in the early twentieth century.
