The island of Corsica was settled by Phoceans traders shortly after their founding of
Massalia on the southeastern coast of France. The Phoceans were active wine growers, cultivating
indigenous vines and
cuttings brought from abroad. In the early
Middle Ages, Corsica first came under the rule of the city of
Pisa in the
Tuscany region, then in the 13th century under that of the
Republic of Genoa. During this time some
ampelographers believe that a clone of the
Sangiovese grape was introduced to the island which became Nielluccio. Over the next 500 years, the Genoese established strict laws governing the harvest and winemaking practices of the island. They also banned all exports of Corsican wines to any port outside of Genoa. The most sought-after wines from Corsica were described as being made in the "
Greek style" from the
Cap Corse region. In 1769, a year after the Genoese ceded control of the island to the French, the Scottish writer
James Boswell praised the diversity and quality of Corsican wines, comparing them favorably to the wines of
Malaga and
Frontignan. That same year, the future French emperor
Napoleon Bonaparte was born in the Corsican city of
Ajaccio to a wine-producing family. Under
Napoleon's rule, Corsica was allowed to export wine and
tobacco duty-free across the
French Empire. In the 19th century, the Corsican government launched several efforts to improve the nation's economy by promoting Corsica's wine industry. These efforts included the widespread planting of the indigenous Sciacarello grape and the construction of a large cellar near the city of
Vizzavona, which was located on the highest point on the railroad line that linked the east coast city of
Bastia with the capital city of Ajaccio. The
phylloxera epidemic of the late 19th century dealt a crippling blow to the Corsican wine industry, and was followed by a period of mass depopulation as Corsicans emigrated to other countries. The Algerian war of Independence ushered in a new period of growth as French
pieds-noirs immigrated to Corsica and began new plantings. During this time, the number of vineyards increased fourfold. The overall quality of Corsican wine was poor due to the emphasis on quantity over quality, with Corsica becoming a prominent contributor to Europe's
wine lake problem. In the 1980s, the
European Union began issuing
subsidies to encourage the uprooting of vines and to renew focus on limited yields and quality wine production. By 2003, these programs had contributed to a reduction of over in the number of vineyard plantings in Corsica, as well as the introduction of modern winemaking techniques and equipment such as temperature-controlled
fermentation tanks. ==Climate and geography==
