Secular is being separate from your religion. Mustafa Kemal made the country of Turkey secular. He did it by getting the muslims of the country not to where fez's or different clothes then everybody else. He thought they should dress alike with the Europeans. Mustafa Kemal was also known as Ataturk. That means father of the turks. He was the president of turkey for 15 years then he died. But he was the one to modernize Turkey. Because of him Turkey is the most modern muslim country in the world!!!
