Grand Duchy of Tuscany in the context of "Treaty of The Hague (1720)"

The House of Medici (English: /ˈmɛdɪtʃi/ MED-itch-ee, UK also /məˈdiːtʃi/ mə-DEE-chee; Italian: [ˈmɛːditʃi]) was an Italian banking family and political dynasty that first consolidated power in the Republic of Florence under Cosimo de' Medici and his grandson Lorenzo "the Magnificent" during the first half of the 15th century. The family originated in the Mugello region of Tuscany, and prospered gradually in trade until it was able to fund the Medici Bank. This bank was the largest in Europe in the 15th century and facilitated the Medicis' rise to political power in Florence, although they officially remained citizens rather than monarchs until the 16th century.

In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ruled the Grand Duchy from its inception under the builder Cosimo I until 1737, with the death of Gian Gastone de' Medici. The Medici produced four popes of the Catholic Church—Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France—Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). The Medici's grand duchy witnessed degrees of economic growth under the early grand dukes, but was bankrupt by the time of Cosimo III de' Medici (r. 1670–1723).

The Duchy of Florence (Italian: Ducato di Firenze) was an Italian principality that was centred on the city of Florence, in Tuscany, Italy. The duchy was founded after Pope Clement VII, himself a Medici, appointed his relative Alessandro de' Medici as Duke of the Florentine Republic, thereby transforming the Republic of Florence into a hereditary monarchy.

The second Duke, Cosimo I, established a strong Florentine navy and expanded his territory, purchasing Elba and conquering Siena. In 1569, Pope Pius V declared Cosimo Grand Duke of Tuscany. The Medici ruled the Grand Duchy of Tuscany until 1737.

The Palazzo Pitti (Italian: [paˈlattso ˈpitti]), in English sometimes called the Pitti Palace, is a vast, mainly Renaissance, palace in Florence, Italy. It is situated on the south side of the River Arno, a short distance from the Ponte Vecchio. The core of the present palazzo dates from 1458 and was originally the town residence of Luca Pitti, an ambitious Florentine banker.

The palace was bought by the Medici family in 1549 and became the chief residence of the ruling family of the Grand Duchy of Tuscany. It grew as a great treasure house, for generations amassing paintings, plates, jewelry and luxurious possessions. The Medici also added the extensive Boboli Gardens to the palace estate.

Franz Joseph I or Francis Joseph I (German: Franz Joseph Karl [fʁants ˈjoːzɛf ˈkaʁl]; Hungarian: Ferenc József Károly [ˈfɛrɛnt͡s ˈjoːʒɛf ˈkaːroj]; 18 August 1830 – 21 November 1916) was Emperor of Austria, King of Hungary, and the ruler of the other states of the Habsburg monarchy from 2 December 1848 until his death in 1916. In the early part of his reign, his realms and territories were referred to as the Austrian Empire, but in 1867 they were reconstituted as the dual monarchy of Austria-Hungary. From 1 May 1850 to 24 August 1866, he was also president of the German Confederation.

In December 1848, Franz Joseph's uncle Emperor Ferdinand I abdicated the throne at Olomouc, as part of Minister President Felix zu Schwarzenberg's plan to end the Hungarian Revolution of 1848. Franz Joseph then acceded to the throne. In 1854, he married his first cousin Duchess Elisabeth in Bavaria, with whom he had four children: Sophie, Gisela, Rudolf, and Marie Valerie. Largely considered to be a reactionary, Franz Joseph spent his early reign resisting constitutionalism in his domains. The Austrian Empire was forced to cede its influence over Tuscany and most of its claim to Lombardy–Venetia to the Kingdom of Sardinia, following the Second Italian War of Independence in 1859 and the Third Italian War of Independence in 1866. Although Franz Joseph ceded no territory to the Kingdom of Prussia after the Austrian defeat in the Austro-Prussian War, the Peace of Prague (23 August 1866) settled the German Question in favour of Prussia, which prevented the unification of Germany from occurring under the House of Habsburg.

Ferdinando de' Medici (9 August 1663 – 31 October 1713) was the eldest son of Cosimo III de' Medici, Grand Duke of Tuscany, and Marguerite Louise d'Orléans. Ferdinando was heir to the Grand Duchy of Tuscany, with the title Grand Prince, from his father's accession in 1670 until his death in 1713. He is remembered today primarily as a patron of music. An excellent musician himself (sometimes called "the Orpheus of princes"), he attracted top musicians to Florence and thus made it an important musical center. Through his patronage of Bartolomeo Cristofori, Ferdinando made possible the invention of the piano.

A grand duchy is a country or territory whose official head of state or ruler is a monarch bearing the title of grand duke or grand duchess.

Prior to the early 1800s, the only Grand duchy in Europe was located in what is now Italy: Tuscany (declared in 1569). During the 19th century there were as many as 14 grand duchies in Europe at once, some of which were revived after the Napoleonic Empire. Some of these were sovereign and nominally independent (Baden, Hesse and by Rhine, Mecklenburg-Schwerin, Mecklenburg-Strelitz, Oldenburg, Saxe-Weimar-Eisenach and Tuscany), some sovereign but held in personal union with larger realms by a monarch whose grand-dukedom was borne as a subsidiary title (Finland, Luxembourg, Transylvania), some of which were client states of a more powerful realm (Cleves and Berg), and some whose territorial boundaries were nominal and the position purely titular (Frankfurt).

The Fourth Ottoman–Venetian War, also known as the War of Cyprus (Italian: Guerra di Cipro; Ottoman Turkish: سفرِ قبرص, romanized: Sefer-i Kıbrıs) was fought between 1570 and 1573. It was waged between the Ottoman Empire and the Republic of Venice, the latter joined by the Holy League, a coalition of Christian states formed by the pope which included Spain (with Naples and Sicily), the Republic of Genoa, the Duchy of Savoy, the Knights Hospitaller, and the Grand Duchy of Tuscany.

The war, the pre-eminent episode of Sultan Selim II's reign, began with the Ottoman invasion of the Venetian-held island of Cyprus. The capital Nicosia and several other towns fell quickly to the considerably superior Ottoman army, leaving only Famagusta in Venetian hands. Christian reinforcements were delayed, and Famagusta eventually fell in August 1571 after an 11-month-long siege. Two months later, at the Battle of Lepanto, the united Christian fleet destroyed the Ottoman fleet, but was unable to take advantage of this victory. The Ottomans quickly rebuilt their naval forces and Venice was forced to negotiate a separate peace, ceding Cyprus to the Ottomans and paying a tribute of 300,000 ducats.

Grand duke (feminine: grand duchess) is a European hereditary title, used either by certain monarchs or by members of certain monarchs' families. The title is used in some current and former independent monarchies in Europe, particularly:

• in present-day Luxembourg, the last surviving Grand Duchy
• historically by the sovereigns of former independent countries, such as Tuscany (from 1569 to 1860, now part of Italy)
• in Baden, Hesse, Oldenburg, Mecklenburg-Schwerin, Mecklenburg-Strelitz and Saxe-Weimar-Eisenach (officially simply the Grand Duchy of Saxony) – grand duchies from 1815 to 1918, and all now part of Germany
• formerly also in some countries in Northern Europe, such as the Grand Duchy of Finland or the Grand Duchy of Lithuania
• currently by claimants to the Russian Imperial Throne (eg. Grand Duke George Mikhailovich of Russia)
