INA, Istituto Nazionale delle Assicurazioni, was a public entity specialized in the Italian monopoly of life insurance; it was established by a decree of the minister Francesco Saverio Nitti in 1912.

[1] On 25 July 1923, Assitalia (Le Assicurazioni d'Italia, Società Anonima) was founded to deal with the non-life branch.

[3] In 1992 the italian government transformed the public entity that manages the INA into a società per azioni with the aim of privatizing the company.

[6] The establishment of the INA Historical Archive was deliberated in April 1961 on the occasion of the celebrations for the fiftieth anniversary of the birth of the Institute.
