Minghetti accepted the suggestion but his efforts to agree with Depretis were vain. Minghetti and Sella were involved into an ambitious program of budget which needed a strong majority, for which they tried to oblige the Independents to choose their side, beginning to build a two-party system as in the United Kingdom. However, in the Italian non-partisan political system, hugely affected by localism and corruption, their bet was equivalent to an all-in that afterwards they lost. The 1874 election did not give to Minghetti the advantage he was hoping, especially for the high support to Depretis's opposition in Southern Italy. Minghetti's government survived, but the bipolarisation of the Parliament he had imposed, strengthened the Left so that it could take the leadership of the country. Two years later, MPs from Tuscany became dissatisfied with the government after it refused to intervene in the financial problems of Florence. The government was defeated on a vote on nationalising railways on 18 March 1876 and Minghetti was forced to resign. As a result, Depretis became Prime Minister, with 414 of the 508 MPs supporting the government. The fall of the Minghetti's cabinet was called, by political commentators, the "parliamentary revolution". Prime Minister of Italy First term On 25 March 1876, Depretis sworn in as Prime Minister; his cabinet was the first one to be composed only by members of the Left. Prominent ministers were Giovanni Nicotera, Pasquale Stanislao Mancini, Michele Coppino, Giuseppe Zanardelli and Benedetto Brin. To strengthen his position, Depretis called for new election in November. For the first time, the left-wing won an election, gaining almost 70% of votes and taking 414 of the 508 seats, of which 12 were extreme left-wingers. As opposed to the previous right-wing governments, whose members were largely aristocrats representing rentiers from the north of the country, and held moderate political views including loyalty to the crown and low government spending, the left-wing government represented the bourgeoisie of the south of the country and supported low taxation, secularism, a strong foreign policy and public jobs. The main reform proposed by the government was the school one that took its name from Minister Coppino and was presented on 15 July 1877. The law introduced compulsory, secular and free primary education for children aged six to nine. On the other hand, while maintaining the electoral promises, Depretis raised the minimum exemption for the mobile wealth tax from 250
