One of the items of the Poljica Statute states that "everyone has the right to live", contrary to many mediaeval European laws replete with capital punishments including torture.
A number of other documents dated from the 12th to 17th century regarding the republic have been preserved, such as Poljički molitvenik (1614) and Statut poljičke bratovštine Sv.Kuzme i Damjana (1619).
The territories of the Republic of Poljica lay chiefly within the south-easterly curve made by the river Cetina before it enters the Adriatic at Omiš.
[4] Didići according to legends are the descendants of three sons of King Miroslav of Croatia (each of them forming a tribe of Tišimiri, Limići and Kremenićani[5]), and were "koljenovići", as they had rights on lands ("didovina").
At a very early date the warlike highlanders of Poljica became the friends and allies of the Omiš corsairs, who were thus enabled to harass the seaborne trade of their neighbors without fear of a sudden attack by land.
A local young woman by the name of Mila Gojsalić became a heroine after sacrificing herself for the good of the Poljica community in one of the conflicts with the Turks—she infiltrated the Turkish camp and blew up the munitions stockpile.
A statue of Mila Gojsalić by Ivan Meštrović stands in Poljica overlooking the mouth of Cetina,[6] and the story was also made into a theatre play.
In the following year, however, the republic incurred the enmity of Napoleon by rendering aid to the Russians and Montenegrins in Dalmatia, and it was invaded by French troops, who plundered its villages, massacred its inhabitants, and finally deprived it of independence.
The early 11-12th century list of rulers is highly doubtful, as the terms "poliscico", "postelnico" and "polstico/i" probably denote Croatian court officier of "postelnik" and not somebody from Poljica, meanwhile others were citizens of Split and are poorly confirmed in historical sources.
