The course analyses the transformation of Italian politics from different levels: the changes of the party system, the electoral laws and the political culture. Special emphasis is put on the Constitutional rules as well as on the political dynamics, involving political parties and social actors. Due consideration is given to the division of powers between institutions (with an eye also on the European and local levels). Special attention is devoted to the role of political parties and of main leaders, also including the new populist trends, with a constant look at current affairs.
