If you remember, I participated in a history convention in April 2010 where I won some prizes. Well today my history teacher told me that my materials were published, then he gave me the actual book. My first subject was "Relationships between tzar Kaloyan and the Latin empire" and the second one, where I had a collaboration with a schoolmate was "IV crusade and its influence on the politics on the Balkans."

Sorry for those who don't understand bulgarian, but I'm not going to translate it, it's just too long.
