Italy under Piedmont with Rome as its capital. It took so long because there were many obstacles to the political unity of Italy. The influence of the Catholic Church was a very significant obstacle but it was one of many, such as the conservative rulers, the lack of popular support for unity and divisions amongst supporters of unity itself. By far the greatest obstacle, however, was the role of Austria in preventing unity.
The Catholic Church was influential in Italy in many ways. Both rulers and ordinary people were influenced by the conservative beliefs of the Catholic
Church and the attitude of the Papacy towards Italian unity was often reflected in the actions of Italian rulers and mass support for nationalism. In 1815 temporal power was restored to the Papacy in the Papal States and the Pope shared the conservatism of the other
Italian rulers who hoped to maintain their own power in individual states. The dominant power in Italy was
Austria and the Habsburg family and they were staunchly Catholic. When there was revolutionary activity in the Papal States in 1831 Austria came to the defence of the Pope.
The conservatism of the Church was therefore an obstacle to unity but up until the 1840s only one of many. Without the Catholic Church the Italian rulers would still have been opposed to greater unity. In the 1820-21 and 1831 revolutions they did not join together to oppose the threat but called upon
Austrian troops to help them. The revolutionaries themselves were also divided over whether unity was desired at all and those who were nationalists had different ideas. For example, Mazzini wanted a united republic and Balbo thought Piedmont should lead a united Italian kingdom. It was the military might of
Austria that maintained the restoration system
