While in Budapest, Murgu befriended several young Aromanians, Megleno-Romanians, and Transylvanians who were studying there, including Andrei Șaguna and Damaschin Bojincă.
He joined a dispute with Sava Tekelija on the Origin of the Romanians, publishing in Buda, in 1830, a work named Widerlegung ("The Rebuttal").
In the Banat, he militated for national and social reforms, suggesting even a union with Wallachia, but he was arrested in March 1845, being freed only 3 years later, on 9 April 1848.
In 1948, Poșta Română issued a 10 lei stamp depicting Murgu together with fellow 1848 revolutionaries, Nicolae Bălcescu, George Bariț, Simion Bărnuțiu, Avram Iancu, and Sándor Petőfi.
