He was one of the founders and most important members of the National Liberal Party.
After the proclamation of the Kingdom of Romania, Ion I. Câmpineanu was appointed the Minister of Foreign Affairs and held the office from February 2, 1885, until October 27, 1885. He was the Mayor of Bucharest from November 1886 to April 1888. He became the first Governor of the National Bank of Romania in July 1880,[1] which he headed until his death on November 13, 1888.

One of the central streets in Bucharest was named after Câmpineanu.[3] In 2015, Poșta Română issued a 3.30 Lei stamp honoring Câmpineanu as the first Governor of the National Bank of Romania.
