Riots start, which lead to a massacre in Aleppo.

The Massacre of Aleppo , often referred to simply as The Events, was a riot perpetrated by Muslim residents of Aleppo, largely from the eastern quarters of the city, against Christian residents, largely located in the northern suburbs of Judayde (Jdeideh) and Salibeh. The riot began on the evening of October 17, 1850, and ended two days later on October 19, 1850. The riot resulted in numerous deaths, including that of Peter VII Jarweh, the Syriac Catholic Patriarch.

October 17 is the 290th day of the year in the Gregorian calendar; 75 days remain until the end of the year.
