The International Day of Human Fraternity was established by the United Nations General Assembly on December 21, 2020, with resolution 75/200[1][2] as a way to promote greater cultural and religious tolerance.

[6] Since it was celebrated for the first time on February 4, 2021,[7] the International Day of Human Fraternity has received endorsements from different world leaders.

Pope Francis;[8] Sheikh Ahmed el-Tayeb, Grand Imam of Al-Azhar;[9] and the President of the United States, Joe Biden,[10][11] have given their support to the initiative.

Pope Francis of the Catholic Church and Sheikh Ahmed el-Tayeb, Grand Imam of Al-Azhar, on February 4, 2019, in Abu Dhabi, United Arab Emirates, signed the Document on Human Fraternity for World Peace and Living Together, also known as the Abu Dhabi declaration.

Finally, the Document on Human Fraternity also influenced the encyclical Fratelli tutti, as Pope Francis acknowledges in the same text by stating that he was inspired to write it by his meeting with Ahmed el-Tayeb in 2019.
