The Association founded several boards (odbori): in Cetinje, in Novi Sad, and in Belgrade. At the same time, the Main Board for Serb Liberation (ÃÂûðòýø þôñþà÷ð ÃÂÃÂÿÃÂúþ þÃÂûþñþÃÂõÃÂõ was established in Kragujevac with the same goals.
The Association was founded by members of the "United Serbian Youth" (ãÃÂõôøÃÂõýð þüûðôøýð ÃÂÃÂÿÃÂúð) and other patriots from all over the Yugoslav lands. This was secretly done after the baptism of Montenegrin Prince Nicholas' daughter.
