Short answers, pulled from the story.
The Ligurian Republic was a French client state formed by Napoleon on the 14th of June 1797, replacing the Republic of Genoa. It covered most of the Ligurian region of Northwest Italy, including small Imperial fiefs previously held by the House of Savoy.
The Ligurian Republic existed from 1797 until June 1805, when it was annexed by the First French Empire as three departements: the Apennins, Genes, and Montenotte. A brief restoration occurred between the 28th of April and the 28th of July 1814, but the territory was then awarded to Piedmont-Sardinia and annexed on the 3rd of January 1815.
The Ligurian Republic used the traditional Genoese flag, a red cross on a white background.
An estimated 30,000 casualties resulted from the Austrian army and British fleet's siege of the Ligurian Republic in 1800. The French army subsequently had to assist with economic restoration.
Archbishop Giovanni Lercari was a Genoese Catholic official who publicly supported the French just three days after Napoleon announced the founding of the Ligurian Republic on the 6th of June 1797. His endorsement helped encourage Genoese cooperation with French rule.
After Napoleon's fall in 1814, the Ligurian Republic was briefly restored between the 28th of April and the 28th of July 1814. Following the Congress of Vienna, the territory was awarded to Piedmont-Sardinia and annexed on the 3rd of January 1815, becoming the Duchy of Genoa within the Savoyard state.
