The Genoese Republic, also known as the Republic of Genoa, was a powerful maritime state in the Mediterranean from the 11th to the 18th centuries. It was centered in the city of Genoa, which became a major trading hub, known for its naval strength and commercial prowess. The republic established colonies and trading posts across the Mediterranean, contributing to its wealth and influence. The government of the Genoese Republic was a complex system that included a council and elected officials. It played a significant role in European politics, often engaging in conflicts with rival states like Venice and Pisa. The republic's decline began in the late 17th century, leading to its eventual incorporation into the Kingdom of Sardinia in 1815.
