San Marino recognizes two official languages: Italian, and Sammarinese. Approximately 83 percent of the population speak Sammarinese, which is considered a variation of the Emiliano-Romagnolo dialect, found in the surrounding Italian region. While Italian is the language of everyday use, phrases and idioms from Sammarinese are used.
Although historically San Marino fought against the political control of the Holy See, most Sammarinese people are Catholic, but there is no state religion. Many of San Marino's official ceremonies are held in the Basilica di San Marino, the republic's main church, or in other churches. There are a total of nine Catholic parishes all of which comprise the diocese of San Marino.
