Partido Nacional Rumano
Maniu joined the Romanian National Party of Transylvania and Banat (PNR), became a member of its collective leadership body in 1897, and represented it in the Budapest Parliament on several occasions. He settled in Blaj, and served as a lawyer for the Greek Catholic Church (to which he belonged). Maniu was influenced by the activity of Simion Bărnuțiu, a maternal uncle of his father, Ioan Maniu.
