Born in Lattarico, Cosenza, Aita became a prominent figure in the post-World War II Italian political landscape. He served as a member of the [[Constituent Assembly of Italy]] from 1946 to 1948, which was tasked with drafting the new constitution for the Italian Republic after the fall of the monarchy. His involvement in this critical period underscores his role in shaping modern Italy's foundational legal framework.
Following his work in the Constituent Assembly, Aita was elected to the [[Chamber of Deputies of Italy]], serving in the first legislature of the Italian Republic from 1948 to 1953. Throughout his political career, he was a staunch representative of the Italian Communist Party, advocating for its policies and contributing to parliamentary debates. He died in Rome in 1960.
