Medici family in the context of "Cosimo III de' Medici, Grand Duke of Tuscany"

Florence (Italian: Firenze) weathered the decline of the Western Roman Empire to emerge as a financial hub of Europe, home to several banks including that of the politically powerful Medici family. The city's wealth supported the development of art during the Italian Renaissance, and tourism attracted by its rich history continues today.

Pietro da Cortona (Italian: [ˈpjɛːtro da (k)korˈtoːna]; 1 November 1596 or 1597 – 16 May 1669) was an Italian Baroque painter and architect. Along with his contemporaries and rivals Gian Lorenzo Bernini and Francesco Borromini, he was one of the key figures in the emergence of Roman Baroque architecture. He was also an important designer of interior decorations.

He was born Pietro Berrettini, but is primarily known by the name of his native town of Cortona in Tuscany. He worked mainly in Rome and Florence. He is best known for his frescoed ceilings, such as the vault of the salone or main salon of the Palazzo Barberini in Rome and carried out extensive painting and decorative schemes for the Medici family in Florence and for the Oratorian fathers at the church of Santa Maria in Vallicella in Rome. He also painted numerous canvases. Only a limited number of his architectural projects were built, but nonetheless they are as distinctive and as inventive as those of his rivals.

Donato di Niccolò di Betto Bardi (c. 1386 – 13 December 1466), known mononymously as Donatello (English: /ˌdɒnəˈtɛloʊ/; Italian: [donaˈtɛllo]), was an Italian sculptor of the Renaissance period. Born in Florence, he studied classical sculpture and used his knowledge to develop an Early Renaissance style of sculpture. He spent time in other cities, where he worked on commissions and taught others; his periods in Rome, Padua, and Siena introduced to other parts of Italy the techniques he had developed in the course of a long and productive career. His David was the first freestanding nude male sculpture since antiquity; like much of his work, it was commissioned by the Medici family.

He worked with stone, bronze, wood, clay, stucco, and wax, and used glass in inventive ways. He had several assistants, with four perhaps being a typical number. Although his best-known works are mostly statues executed in the round, he developed a new, very shallow, type of bas-relief for small works, and a good deal of his output was architectural reliefs for pulpits, altars and tombs, as well as Madonna and Childs for homes.

Catherine de' Medici (Italian: Caterina de' Medici, pronounced [kateˈriːna de ˈmɛːditʃi]; French: Catherine de Médicis, pronounced [katʁin də medisis]; 13 April 1519 – 5 January 1589) was an Italian Florentine noblewoman of the Medici family and Queen of France from 1547 to 1559 by marriage to King Henry II. She was the mother of French kings Francis II, Charles IX, and Henry III, and a cousin to Pope Clement VII. The years during which her sons reigned have been called "the age of Catherine de' Medici" since she had extensive, albeit at times varying, influence on the political life of France.

Catherine was born in Florence to Lorenzo de' Medici, Duke of Urbino, and his wife, Madeleine de La Tour d'Auvergne. In 1533, at the age of 14, Catherine married Henry, the second son of King Francis I and Queen Claude of France, who would become Dauphin of France (heir to the throne) upon the death of his elder brother Francis in 1536. Catherine's marriage was arranged by Clement VII. Henry largely excluded Catherine from state affairs during his reign, instead showering favours on his chief mistress, Diane de Poitiers, who wielded significant influence in the court. Henry's sudden accidental death in 1559 thrust Catherine into the political arena as mother of the frail 15-year-old Francis II. When Francis II died the next year, she became regent on behalf of her 10-year-old son Charles IX and thus gained sweeping powers. After Charles died in 1574, Catherine played a key role in the reign of her third son, Henry III. He dispensed with her advice only in the last months of her life but outlived her by just seven months.

The Medici Bank (Italian: Banco dei Medici [ˈbaŋko dei ˈmɛːditʃi]) was a financial institution created by the Medici family in Italy during the 15th century (1397–1494). It was the largest and most respected bank in Europe during its prime. There are some estimates that the Medici family was, for a period of time, the wealthiest family in Europe. Estimating their wealth in today's money is difficult and imprecise, considering that they owned art, land, and gold. With this monetary wealth, the family acquired political power initially in Florence, and later in the wider spheres of Italy and Europe.

A notable contribution to the professions of banking and accounting pioneered by the Medici Bank was the improvement of the general ledger system through the development of the double entry system of tracking debits and credits or deposits and withdrawals.

The Duca della Repubblica Fiorentina, rendered in English as Duke of the Florentine Republic or Duke of the Republic of Florence, was a title created in 1532 by Pope Clement VII for the Medici family (his own family), which ruled the Republic of Florence. There were effectively only two dukes of the Republic of Florence, Alessandro de' Medici and Cosimo de' Medici, the second duke being elevated to Grand Duke of Tuscany, causing the Florentine title to become subordinate to the greater Tuscan title.
