The special attention that this article devotes to Bulgarian Muslim Turks is due to at least three important issues: first, this is the second largest ethnic and religious group in the country after the Bulgarian Christian majority, and the problems of this community involve a large portion of the population; second, geopolitical circumstances make this group a significant factor for Bulgaria; third, the Islamic religion is of growing political importance in the world: all of these determine some of the emphasis in the following discussion. We have focused specially on the characteristics and regularities of the neighborhood of the Muslim community with the majority; the reverse connection is examined as a correlative; comparisons with other religious communities have been made only if necessary for specific comparisons.
