After unification, Italy's politics favored liberalism: the Liberal-conservative right (Destra storica or Historical right) was regionally fragmented, and Liberal-conservative Prime Minister Marco Minghetti only held on to power by enacting revolutionary and left-leaning policies (such as the nationalization of railways) to appease the opposition.
In 1876, Minghetti was ousted and replaced by Liberal Agostino Depretis, who began the long Liberal Period. The Liberal Period was marked by corruption, government instability, continued poverty in southern Italy, and use of authoritarian measures by the Italian government. Depretis began his term as Prime Minister by initiating an experimental political idea called Trasformismo (transformism). The theory of trasformismo was that a cabinet should select a variety of moderates and capable politicians from a non-partisan perspective. In practice, trasformismo was authoritarian and corrupt, Depretis pressured districts to vote for his candidates if they wished to gain favourable concessions from Depretis when in power.
The results of the Italian general election of 1876 resulted in only four representatives from the right being elected, allowing the government to be dominated by Depretis. Despotic and corrupt actions are believed to be the key means in which Depretis managed to keep support in southern Italy. Depretis put through authoritarian measures, such as banning public meetings, placing "dangerous" individuals in internal exile on remote penal islands across Italy and adopting militarist policies. Depretis enacted controversial legislation for the time, such as abolishing arrest for debt, making elementary education free and compulsory while ending compulsory religious teaching in elementary schools.
In 1887, Francesco Crispi became Prime Minister and began focusing government efforts on foreign policy. Crispi worked to build Italy as a great world power through increased military expenditures, advocacy of expansionism and trying to win the favour of the German Empire. Italy joined the Triple Alliance which included both Germany and Austria–Hungary in 1882 and which remained officially intact until 1915. While helping Italy develop strategically, he continued trasformismo and was authoritarian, once suggesting the use of martial law to ban opposition parties. Despite being authoritarian, Crispi put through liberal policies such as the Public Health Act of 1888 and establishing tribunals for redress against abuses by the government.
