Morean War in the context of "Acropolis of Athens"

A series of military conflicts between the Ottoman Empire and various European states took place from the Late Middle Ages up through the early 20th century. The earliest conflicts began during the Byzantine–Ottoman wars, waged in Anatolia in the late 13th century before entering Europe in the mid-14th century with the Bulgarian–Ottoman wars. The mid-15th century saw the Serbian–Ottoman wars and the Albanian-Ottoman wars. Much of this period was characterized by the Ottoman expansion into the Balkans. The Ottoman Empire made further inroads into Central Europe in the 15th and 16th centuries, culminating in the peak of Ottoman territorial claims in Europe.

The Ottoman–Venetian wars spanned four centuries, starting in 1423 and lasting until 1718. This period witnessed the fall of Negroponte in 1470, the siege of Malta in 1565, the fall of Famagusta (Cyprus) in 1571, the defeat of the Ottoman fleet at the Battle of Lepanto in 1571 (at that time the largest naval battle in history), the fall of Candia (Crete) in 1669, the Venetian reconquest of Morea (Peloponnese) in the 1680s and its loss again in 1715. The island of Venetian-ruled Corfu remained the only Greek island not conquered by the Ottomans.

The Ottoman–Venetian wars were a series of conflicts between the Ottoman Empire and the Republic of Venice that started in 1396 and lasted until 1718. It included:

• Venice's participation in the Crusade of Nicopolis in 1396
• A naval conflict in 1415–1419, the main event of which was the Battle of Gallipoli (1416)
• The Siege of Thessalonica (1422–1430), with Venice active from 1423 on, resulting in the capture of Thessalonica by the Ottomans
• The First Ottoman–Venetian War (1463–1479), resulting in the capture of Negroponte, Lemnos and Albania Veneta by the Ottomans
• The Second Ottoman–Venetian War (1499–1503), resulting in the capture of the Venetian strongholds in the Morea (Peloponnese) by the Ottomans
• The Third Ottoman–Venetian War (1537–1540), resulting in the capture of the Cyclades except Tinos, the Sporades and the last Venetian strongholds in the Morea (Peloponnese) by the Ottomans
• The Fourth Ottoman–Venetian War (1570–1573), resulting in the capture of Cyprus by the Ottomans, and the defeat of their fleet in the Battle of Lepanto (1571)
• The Fifth Ottoman–Venetian War or the Cretan War (1645–1669), resulting in the capture of Crete by the Ottomans
• The Sixth Ottoman–Venetian War or the Morean War (1684–1699), resulting in the capture of the Morea (Peloponnese), Lefkada, Aigina and parts of Dalmatia by Venice and the end of Ottoman dominance in the eastern Mediterranean Sea
• The Seventh and last Ottoman–Venetian War (1714–1718) (also called the Second Morean War or Sinj war), resulting in the recapture of the Morea (Peloponnese) and of Tinos and Aigina, the last Venetian holdings in the Aegean, by the Ottomans

The Kingdom of the Morea or Realm of the Morea (Italian: Regno di Morea; Venetian: Regno de Morea; Greek: Βασίλειον του Μορέως, romanized: Vasíleion tou Moréos) was the official name the Republic of Venice gave to the Peloponnese peninsula in Southern Greece (which was more widely known as the Morea until the 19th century) when it was conquered from the Ottoman Empire during the Morean War in 1684–99. The Venetians tried, with considerable success, to repopulate the country and reinvigorate its agriculture and economy, but were unable to gain the allegiance of the bulk of the population, nor to secure their new possession militarily. As a result, it was lost again to the Ottomans in a brief campaign from June to September in 1715.

The Croats of Bosnia and Herzegovina (Croatian: Hrvati Bosne i Hercegovine), often referred to as Bosnian Croats (bosanski Hrvati) or Herzegovinian Croats (hercegovački Hrvati), are native to Bosnia and Herzegovina and constitute the third most populous ethnic group, after Bosniaks and Serbs. They are one of the three constitutive nations of Bosnia and Herzegovina. Croats of Bosnia and Herzegovina have made significant contributions to the culture of Bosnia and Herzegovina. Most Croats identify themselves as Catholics and speak Croatian language.

Croats have been present in Bosnia and Herzegovina since the Slavic migrations to the Balkans. The Kingdom of Croatia under native rulers and later in personal union with Hungary encompassed large parts of Bosnia and Herzegovina in the west until the 16th century. The Croats also lived under the Kingdom of Bosnia until it fell to the Ottoman Empire in the second half of the 15th century. Between the 15th and 19th centuries, Catholics in Ottoman Bosnia and Herzegovina were often persecuted by the Ottomans, prompting many to flee the area, especially during the Great Turkish War and the Morean War in the second half of the 17th century, when their numbers were reduced to 30,000. At the end of the 17th century and in the early 18th century, the number of Catholics began to increase, with many of those who had fled returning. In the second half of the 19th century, especially during the Austro-Hungarian rule in Bosnia and Herzegovina, the Croats became active political subjects, participating in Croatian national revival. The 20th century brought political turmoil, and poor economic conditions led to increased emigration. Ethnic cleansing within Bosnia and Herzegovina in the 1990s saw Croats forced to go to different parts of Bosnia and Herzegovina, despite having lived in numerous regions before the Bosnian War. The 2013 population census in Bosnia and Herzegovina recorded 544,780 residents registering as of Croat ethnicity.

The Venetian patriciate (Italian: Patriziato veneziano, Venetian: Patrisiato venesian) was one of the three social bodies into which the society of the Republic of Venice was divided, together with citizens and foreigners. Patrizio was the noble title of the members of the aristocracy ruling the city of Venice and the Republic. The title was abbreviated, in front of the name, by the initials N.H. (Nobilis Homo or Nobiluomo), together with the feminine variant N.D. (Nobilis Domina). Holding the title of a Venetian patrician was a great honour and many European kings and princes, as well as foreign noble families, are known to have asked for and obtained the prestigious title.

The patrician houses, formally recorded in the Golden Book, were primarily divided into Old Houses (Case vecchie) and New Houses (Case nuove), with the former being noted for traditionally electing the first Doge in 697 AD. The New Houses were no less significant, as many became very prominent and important in the history of the Republic of Venice. The families were furthermore divided into several other "categories", including Ducal Houses (Case ducali, whose members had become Doges), Newest Houses (Case nuovissime) raised to the patriciate in 1381, non-Venetian patrician families, and "Houses made for money" (Case fatte per soldo, usually wealthy landowning or bourgeoisie families who contributed to the state during the War of Candia and the Morean War).
