The origins of the Papal States date back to the 9th century when it was founded with the help of Charlemagne, emperor of France.
It stopped being such when in 1870 Vittorio Emanuele of Savoy author of the unification of the Kingdom of Italy occupied the papal territory and declared Rome as the capital of Italy.
According to Abbreviationfinder, an acronym site which also features history of Vatican City State, the King established the Pope’s inviolability and possession of the Vatican in 1871.
However, the popes did not accept this situation until February 11, 1929 when the Holy See signed the Treaty of the Lateran Pacts with Benito Mussolini in which the limits and privileges of the current Papal States were established.
In the Lateran Pacts a monetary compensation of 1750 million lire was established as compensation for the territories lost in 1870.
In 1993 two important events occurred. The workers of the Vatican, for the first time, protested for higher wages and pensions. During the trip to the United States of America, in June, the Pope authorized the use of his image for commercial purposes, authorizing the sale of posters and T-shirts with his image. This raised the economic conditions of the state.
