All began after the alleged attempted Coup d'état (stroke of state) last year.
I said alleged because there are many rumors that president Erdogan organized it in order to justify restriction of political freedom and democracy in Turkey.
After that event Erdogan, without any trial, closed many political opponents and journalists and he dismissed many soldiers, policemen and teachers.
It's the first time in the last 100 years of history that Turkey has returned from the path of democracy to the dictatorship of Sultans.
