* tzar - In Cyrillic цар/царь, is a title originating from the Latin word caesar, meaning emperor. The first ruler to adopt it was Bulgarian tzar Simeon I (893 - 927), under whose rule that the Cyrillic was developed and put in use. The earliest text mentioning the title is Mostich's epitaph.

We see that Albena says, that people will talk regardless and that there are talks that could be avoided, to which Vulchan agrees, despite believing them as mere superstitions. Slavic people even today, perform certain actions when there is a deceased in the house, such as leaving the light on, covering the mirrors, so that the soul does not look upon its own reflection and decides to come back, open the windows and door so that the soul can freely go out, spent the whole night with the dead one's body, etc. I recall, being told by an acquaintance, that their grandmother and her sisters would take turns and sleep in the house of their passed away sister until 40 days after her death had passed because it was tradition. Cats, dogs and roosters would be kept away, otherwise, there would be a possibility they'd jump over the body and the dead one might return as a vampire. 

South Slavs - Bosnians, Bulgarians,Croatians, Macedonians, Montenegrins, Serbs, and Slovenians, believe that if a person is not buried or mourned according to traditions they'll return as a vampire. People that were also likely to return as vampires were those who while still living practised magic, led sinful life, and died obscenely or unnaturally.

To make sure one wouldn't come back, people would cut the head off and place it between the legs, cut the feet and hands off, so that they couldn't walk and do evil, as there is a belief that vampires can change the course of rivers, cause plagues and draught. A stake would be put through the heart, while a stone - be between the teeth. 

There is a popular belief that people born on a Saturday could recognise vampires among other supernatural beings.
