One of the most fervent contemporary critic of his infallibility dogma, Ignaz von Döllinger, considered the "political regime" of the pope in the Papal States as "wise, well-intentioned, mild-natured, frugal and open for innovations".
After the revolution however, his political reforms and constitutional improvements were considered minimalists, remaining largely within the framework of the 1850 laws mentioned above[3] The governmental structure of the Papal States reflected the dual spiritual-secular character of the papacy at the time.
But the clergy occupied the key decision making positions and every job applicant had to present a character evaluation from his Parish priests in order to be considered.
[5] The tax burden of the citizens was far below European average, which resulted in an influx of foreign residents into Rome, many of them non-Catholics, which created local problems with religious services and their integration.
[6] The criticism of the economic policies of Pius IX included the argument that the Pope maintained in Rome large areas for agriculture and forestry at the expense of potential industrial development.
Pius IX is credited with systematic efforts to improve manufacturing and trade by giving advantages and papal prizes to domestic producers of wool, silk and other materials destined for export.
[9] This problem, immortalized by Alessandro Manzoni's The Betrothed, and vividly described by the English Cardinal Nicholas Wiseman, existed long before Pius IX.
[9] A unique position was granted to the Papal army, consisting almost exclusively of foreigners, since the Roman Black Nobility was not willing to serve and the population resisted military service as well, despite a decent salary structure and the potential for promotion.
However, the Austrian and French troops did not always behave like model Christians, creating resentments in the local population and furthering the nationalistic tendencies towards a unified Italy, free of any foreigners.
During his reign, Pius IX undertook innovative efforts: he created new schools for the handicapped and evening academies for persons to improve their education after working hours.
[10] The two papal universities in Rome and Bologna suffered much from the revolutionary activities in 1848 but their standards in the areas of science, mathematics, philosophy and theology were considered adequate.
He created a new clinic for pregnant women to give birth, several museums, and a Papal astronomical observatory[10] Theology students were subjected to more rigorous training.
He generously supported all expressions of art, architecture, painting, sculpture, music, goldsmiths, coppersmiths and more, and handed out numerous rewards to its representatives.
Italian nationalism had been stoked during the Napoleonic period but dashed by the settlement of the Congress of Vienna (1814–15), which left Italy divided and largely under Habsburg Austrian domination.
In 1848, nationalist and liberal revolutions began to break out across Europe; in 1849, a Roman Republic was declared and Pope Pius IX fled the city.
Louis Napoleon Bonaparte, recently elected president of the newly declared French Second Republic, saw an opportunity to assuage conservative Catholic opinion in France, and in cooperation with Austria sent troops to restore Papal rule in Rome.
After some hard fighting (in which Giuseppe Garibaldi distinguished himself on the Italian side), Pius was returned to Rome, and repenting of his previous liberal tendencies pursued a harsh, conservative policy even more repressive than that of his predecessors.
After the Second Italian War of Independence, much of northern Italy was unified under the House of Savoy's government; in the aftermath, Garibaldi's expedition of the Thousand overthrew the Bourbon monarchy in the Kingdom of the Two Sicilies.
Afraid that Garibaldi would set up a republican government in the south, the Sardinians petitioned Napoleon for permission to send troops through the Papal States to gain control of the Two Sicilies, which was granted on the condition that Rome was left undisturbed.
By the September Convention of 1864, Napoleon III agreed to withdraw French forces from Rome in return for Italy respecting the borders of the rump Papal States and moving its capital to Florence.
Emperor Napoleon III had to recall his garrison from Rome for France's own defence and could no longer protect the pope, following the collapse of the Second French Empire at the Battle of Sedan.
Although the pope's tiny army was incapable of defending the city, Pius IX ordered it to put up at least a token resistance to emphasize that Italy was acquiring Rome by force and not consent.
The Italian government had offered to allow the Pope to retain control of the Leonine City on the west bank of the Tiber, but Pius rejected the overture.
The Pope, whose previous residence, the Quirinal Palace, had become the royal palace of the kings of Italy, withdrew in protest into the Vatican, where he lived as a self-proclaimed "prisoner", refusing to leave or to set foot in St. Peter's Square, and forbidding (Non Expedit) Catholics on pain of excommunication to participate in elections in the new Italian state, an action which effectively guaranteed that only persons hostile to the Catholic Church would be involved in the new government.
