The Maritime Republic of Pisa was one of the four maritime republics of Italy, along with Venice, Genoa, and Amalfi. During the 11th and 13th centuries, Pisa experienced a period of great splendor and power. Its strategic location in the Tyrrhenian Sea allowed it to develop a powerful naval fleet and establish trade routes that expanded throughout the Mediterranean. Pisa became an important commercial and financial center, and its citizens amassed great wealth through maritime trade. During this period, notable architectural works were constructed, such as the famous Leaning Tower of Pisa. However, over time, Pisa's power waned due to conflicts with other city-states and the loss of many of its colonies in the Mediterranean. Ultimately, Pisa was conquered by Florence in 1406.
