In spite of the fact that you have not provided the map, to the best of my knowledge, Italy was fully united in 1871 because In 1870, the Italian army annexed Rome and the Papal States. These additions provided Italy nearly its current boundaries, and the city of Rome became the Italian capital.
The Republican Constitution was approved on 1 January 1948.Under The Treaty of Peace with Italy of 1947,most of Julian March was lost to Yugoslavia,and later The Free Territory of Trieste was divided between the two states.Italy also lost all of its colonial possessions,formally ending the Italian Empire.
