Here is some more information: November, 1st is the day of the leaders of the Bulgarian National Revival. The day is devoted to the bookmen, the enlighteners, the fighters for national liberation who have preserved through the centuries the spiritual values of the nation and its moral. The National Revival is a period when Bulgarians gathered spiritual and intellectual strength to establish their right of independent political and social existence, and their own culture and education. Outstanding figures of the Bulgarian National Revival, most of them educated abroad, gradually arrived at the idea of opening a school of higher education, which would make Bulgarians equal with other politically independent, socially organised and culturally emancipated nations. 
The day is marked for the first time in Plovdiv in 1909 but in 1945 the celebration is banned. The marking of the day of Bulgaria’s enlighteners is restored in 1992. Some of the most popular Revival Leaders are Paisii Hilendarski, Ivan Vazov, Lyuben Karavelov, Georgi Rakovski, Vasil Levski, Hristo Botev, Dobri Chintulov.
