Diocese of San Miniato
diocese of the Catholic Church in Italy

The Diocese of San Miniato (Latin: Dioecesis Sancti Miniati) is a Latin diocese of the Catholic Church in Tuscany. It is a suffragan of the archdiocese of Florence.
History
In 1248, San Genesio was completely destroyed. In 1397, the town was taken by Florence, and was placed under the control of a vicar appointed by the government of Florence. From 21 January 1529 to November 1530, San Miniato was attacked and besieged by Spanish forces. More than 300 inhabitants were killed.
From 1248, the Chapter of the collegiate church of San Genesio was transferred to San Miniato, and in 1527 the head of the Chapter was granted the privilege of wearing pontifical vestments, the mitre, and the use of the pastoral staff, inside the territory of San Miniato. In 1408, the Republic of Florence wished to have it made an episcopal see, being then a territory in the archdiocese of Lucca, but the effort failed.
The situation changed when Maria Maddelena of Austria, the wife of Duke Cosimo II of Tuscany took up residence in S. Miniato, and made herself its patron. She successfully put pressure on Pope Gregory XV. On 5 December 1622, the town (oppidum) of San Miniato was raised to the dignity of a city (civitas), and was named the seat of a bishop by Pope Gregory XV. The church of S. Maria and S. Genesius was elevated to the status of a cathedral.
