Turkey's Prime Minister Recep Tayyip Erdogan and his AK party have proposed eliminating the schools, which provide private tuition classes to help high school children prepare for university entrance exams.
This has angered supporters of the Gulen movement, which finances and runs many of the schools. Numerous hashtags about the row have been tweeted millions of times over the past week.
#BBCtrending reports that the row points to deeper tensions between Mr Erdogan and the Gulen movement.
