International PEN is a worldwide association of writers dedicated to promoting literature and defending freedom of expression. Founded in 1921, it connects writers from various countries to support each other and advocate for the rights of those facing censorship or persecution due to their work. The organization works through a network of national centers, each focusing on local issues while contributing to global campaigns. International PEN also organizes events, awards, and initiatives to raise awareness about the importance of free speech and the role of literature in society.
