The book Operação Viragem Histórica – 25 de Abril de 1974, coordinated by Carlos de Almada Contreiras, provides a clear and rigorous analysis of the events that led to the Carnation Revolution. The work highlights the military planning and the historical importance of April 25 in the construction of democracy in Portugal.

The 3rd edition, commemorating the 50th anniversary of April 25, was one of the works donated to our collection this year and is available for consultation in the reading room.
