The Italian Constitution

The Turkish Constitution is similar to the German Constitution organically, both of them firstly prescribes freedoms and rights of people, then regulates organisation of state. But the virtue and main principles of the Turkish Constitution matches with the French Constitution. Both of them shows that the states are unite and nondivisible, secular and social states. Apart from the German, Dutch, Italian and Turkish Constitutions the Austrian and French Constitutions does not regulate freedoms and rights with details. They regulate especially the government and main principles of state. Also Italian Constitution prescribes that the state and church are independent and relations between them are regulated with paxes in other words agreement. So Italy is not sovereign against to the church but this does not show that Italy is not secular. Secularism in Europe, has been adopted in a long process and mainly functional. Society live and government of state and law is not be regulated by religion and church. But the constitutions of states which had been established after a revolution like France and Turkiye, says expressly "the state is secular"
Except France and Türkiye many other European states are decentralised, as a federation or any other autonomous administration.
