The Republic of Genoa was a powerful maritime republic in northern Italy, established in the 11th century. It played a significant role in trade and commerce in the Mediterranean Sea, competing with other city-states like Venice and Pisa. The republic was known for its strong navy and extensive trading networks, which helped it become one of the wealthiest cities in Europe. At its height, the Republic of Genoa controlled various territories, including parts of Corsica and Sardinia. The republic's influence declined in the 18th century, leading to its eventual incorporation into the Kingdom of Sardinia in 1815. Today, Genoa is the capital of the Liguria region and a major port city.
