On 30 May 1922, Latvia and the Holy See sign the Concordat — the agreement regulating the status of the Catholic Church in the independent Baltic republic.

Signatories: Foreign Minister Zigfrīds Meierovics and Cardinal Pietro Gasparri. Ratifications were exchanged at the Vatican on 3 November 1922; the text was registered in the League of Nations Treaty Series in 1923.

The Concordat elevates the Diocese of Riga to an archdiocese, requires bishops of Latvian nationality, gives the government a veto over candidates and binds bishops to swear allegiance to Latvian law.

The Church receives legal personality, its own schools, a seminary in Latvian and clergy exemption from military service. A supplementary protocol amended the text in 1938; it was replaced by a new agreement in 2000.

For interwar Latvia, 30 May 1922 meant diplomatic recognition of the relationship with Rome after centuries of dominant Protestantism.

The text appears in Acta Apostolicae Sedis and in LNTS vol. 17.

The Concordat of 30 May 1922 remains the founding act of Latvia–Vatican relations in the interwar period.
