Day of the Imprisoned Writer oder Writers in Prison Day is celebrated on November 15, 2017. The Day of the Imprisoned Writer is an annual, international day intended to recognize and support writers who resist repression of the basic human right to freedom of expression and who stand up to attacks made against their right to impart information. It was started in 1981 by International PEN's Writers in Prison Committee.
In addition to increasing the public's awareness of persecuted writers in general, PEN uses the Day of the Imprisoned Writer to direct attention to several specific persecuted or imprisoned writers and their individual circumstances. Each of the selected writers is from a different part of the world, and each case represents circumstances of repression that occur when governments or other entities in power feel threatened by what writers have written.
On this day, the general public is encouraged to take action—in the form of donations and letters of appeal on behalf of the selected writers. The day also serves to commemorate all of the writers killed since the previous year's Day of the Imprisoned Writer. (With material from: Wikipedia)
