Danish municipalities have a longstanding tradition of uniting in communities of interest. KL is an interest and member organisation for the Danish municipalities and has existed since 1970.
KL is a result of the local government reform in Denmark in 1970 where 1,336 municipalities were reduced to only 275.
As a result of the reform in 1970, the three local government associations (for different sizes of municipalities), that existed at that time, decided to join forces and founded what is today KL - Local Government Denmark (KL).
Since 2005, all of the Danish municipalities are members for KL.
The 1st of January 2007, a new Local Government Reform came into force, reducing the number of municipalities to 98 and redistributing responsibilities for several welfare task – primarily granting the new and larger 98 municipalities more tasks and responsibilities.
