Plural of concordat; formal agreements, especially between governments or between the Vatican and a nation.
From Medieval Latin concordatum (agreement), past participle of concordare (to agree together). Historically used for papal treaties and later for any formal agreement between states.
The most famous concordat is probably the Lateran Treaty of 1929, which established Vatican City as an independent state—these aren't casual agreements but major historical documents that reshape the political landscape.
