Gritti’s father lived in Istanbul as a grain merchant for about twenty years before returning as a diplomat on behalf of Venice. During this time he had multiple sons with a Greek, possibly Turkish, concubine. The commonly cited number is four, Pietro, Alvise, Lorenzo, and Zorzi; however, Eric Dursteler mentions only three, citing one of Gritti's father's political opponents who argued that "one who has three bastard sons in Turkey should not be made Doge." Given that names exist for four sons, it seems more likely that this piece of political invective left out a son than that historians have added a fourth. Regardless, Gritti spent his childhood in Constantinople. Gritti studied at the University of Padua, likely after traveling from Istanbul with his father in 1502. As an illegitimate child, Gritti was unable to hold high-ranking positions in Venice, but this barrier did not exist in Istanbul, to which he returned in 1506.
Early career
Stationing himself in Galata, across the Golden Horn from Istanbul, Gritti became involved in banking and trade, particularly with Venice. Though trading in a variety of goods, such as saltpeter, salt milk, clothes, saffron, tin, and wine, grain and gems were some of Gritti’s most prominent ventures. The former was imported to Venice, while the latter found a patron in the sultan. Gritti was thus involved in the creation and presentation of Suleiman the Magnificent’s golden Venetian helmet-crown. His success was evidenced by his luxurious palazzo, with expansive gardens, stables, and numerous servants, stables, as well as by extravagant garments and jewelry. His court was host to feasts and entertainments, as well as Italian merchants and humanists. The origins of Gritti’s relationship with Ibrahim Pasha, who was appointed Grand Vizier to Suleiman in 1523, are unclear, but Gritti won favor with Ibrahim, who entrusted him with great responsibilities, making him a business partner. It is possible that Ibrahim Pasha was influenced by his childhood ties to Venice, as he was born on the Venetian island of Parga. Regardless, Ibrahim Pasha seems to have sought Gritti’s opinion on matters pertaining to foreign policy and him and the sultan are known to have visited Gritti’s house in Galata. Also in 1523 Gritti’s father ascended to the position of doge of Venice, a move that furthered Gritti’s political power. Gritti was known as the “Prince’s Son” and was likely partially responsible for Ibrahim Pasha’s favorable policies towards Venice. In 1527 Gritti supported King John I of Hungary against Ferdinand I of Habsburg, who wanted the crown for himself. He soon became one of the most important allies of King John and served as ambassador between the monarch and the Turkish sultan. In 1528 the grand vizier, according to reports, planned to take him on the projected campaign into Hungary where Gritti was to get "an important archbishopric plus a piece of the archduchy of Austria once the Turks had taken them." Lodovico stayed in the city ofBuda first as King John's advisor, and then between 1530 and 1534 as regent of Hungary.
Attempted coup
On 9 November 1533, the governor of Marano wrote to Charles V, Holy Roman Emperor, "I heard a few days ago that the Captain-General of Croatia apprehended and sent to Ljubljana two of Gritti's spies. They have confessed that Gritti, in the name of the Turkish Emperor, has made an alliance with the kings of England and France and also with several other princes against His Imperial and Royal Majesties of Hesse will create disturbances in Germany, and so distress Christendom that His Imperial Majesty will find himself in trouble." Gritti's attempt to take over Transylvania caused a general uprising but in the end he was killed along with his two sons at the siege of Medgyes. His remains were buried in the church of St. Francis in Mediaș in modern-day Romania.
