Question: In which province was the state that Piero di Tommaso Soderini served as a statesman in?
Context: Piero di Cosimo de' Medici (the Gouty), (Italian: "Piero "il Gottoso"") (1416 – 2 December 1469) was the "de facto" ruler of Florence from 1464 to 1469, during the Italian Renaissance. Giovanni di Bicci de' Medici (c. 1360 – February 20/28, 1429) was an Italian banker, a member of Medici family of Florence, and the founder of the Medici Bank.  While other family members, such as Chiarissimo di Giambuono de' Medici, who served in the Signoria in 1201, and Salvestro de' Medici, who was implicated in the Ciompi Revolt of 1378, are historically significant, Giovanni's founding of the family bank truly began the family's rise to power in Florence.  He was the father of Cosimo de' Medici ("Pater Patriae"), grandfather of Piero di Cosimo de' Medici, great-grandfather of Lorenzo de' Medici (the Magnificent) and great-great-great-grandfather of Cosimo I de' Medici, Grand Duke of Tuscany. Piero di Cosimo (2 January 1462 – 12 April 1522), also known as Piero di Lorenzo, was a Florentine painter of the Italian Renaissance. Lorenzo Monaco (born Piero di Giovanni; 1370 – c. 1425) was an Italian painter of the late Gothic-early Renaissance age.  He was born Piero di Giovanni in Siena.  Little is known about his youth, apart from the fact that he was apprenticed in Florence.  He was influenced by Giotto and his followers Spinello Aretino and Agnolo Gaddi. Niccolò di Piero Lamberti (ca. 1370 – 1451), also known as Niccolò di Pietro Lamberti, Niccolo Aretino, Niccolò d'Arezzo and as il Pela, was an Italian sculptor and architect.  Little is known about his life other than that he was married in Florence in 1392.  His son, Piero di Niccolò Lamberti (1393–1435), was also a sculptor, and the two are notable for exporting the Tuscan style of sculpture to Venice, where they were active in the late 1410s and 1420s. Francesco di Tommaso Soderini (10 June 1453–17 May 1524) was a major diplomatic and Church figure of Renaissance Italy, and brother of Piero Soderini.  He was an adversary of the Medici family. The Republic of Florence, also known as the Florentine Republic (Italian: "Repubblica Fiorentina" ; ] ), was a medieval and early modern state that was centered on the Italian city of Florence in Tuscany.  The republic originated in 1115, when the Florentine people rebelled against the Margraviate of Tuscany upon the death of Matilda, a woman who controlled vast territories including Florence.  The Florentines formed a commune in her successors' place.  The republic was ruled by a council, known as the signoria.  The signoria was chosen by the "gonfaloniere" (titular ruler of the city), who was elected every two months by Florentine guild members. Piero di Tommaso Soderini (May 18, 1450 – June 13, 1522) also known as Pier Soderini, was an Italian statesman of the Republic of Florence. Piero di Lorenzo de' Medici (15 February 1472 – 28 December 1503), called Piero the Unfortunate, was the Gran maestro of Florence from 1492 until his exile in 1494. Nannina de' Medici (14 February 1448 – 14 May 1493), born Lucrezia de' Medici, was the second daughter of Piero di Cosimo de' Medici and Lucrezia Tornabuoni.  She was thus the elder sister of Lorenzo de' Medici.  She married Bernardo Rucellai.  Her father's name was Piero, so she is sometimes known as Lucrezia di Piero de' Medici.
