It is considered that most of the dolmens were used for burying a chief or ruler of that society because quarrying, moving capstones and large stone blocks required intensive labours Employing and managing many people required a certain political power and substantial amount of wealth could afford to build dolmens .
As a group of dolmens forming an aggregated cluster, it is unlikely that they all were made to single individual. Thus limited number of people who held political power and substantial amount of wealth could afford to build dolmens.
A group of dolmen was considered family tomb because they are aggregated in group or distributed in a row.
There are some cases that stone daggers and stone arrowhead were found in the burial chamber of dolmens. Such artefacts found in the area where head was assumed to have been placed. Therefore it is suggested that the buried men were the war deads deeply injured by weapons. In Korea, human skeleton without the head part was found inside the chamber and in Japan, a fragment of bronze weapons and pieces of stone daggers embedded in the head were found.
