The title of Duke of Abrantès was a title of Napoleonic nobility created in 1808 by Napoleon for Jean-Andoche Junot.
After the King of Portugal's refusal to join the Continental Blockade, Napoleon I despatched General Jean-Andoche Junot in command of the French invasion of Portugal. General Junot marched through Portugal and set up camp at the city of Abrantes, before advancing on Lisbon.
The Ribatejo (Portuguese pronunciation: [ʁiβɐˈtɛʒu]) was the most central of the traditional provinces of Portugal, with no coastline or border with Spain. The region is crossed by the Tagus river (Ribatejo translates to "upper Tagus", or more precisely, "up the Tagus" relative to Lisbon at its mouth). The region contains some of the nation's richest agricultural land, and it produces most of the animals used in the Portuguese style of bullfighting.
Ribatejo Province was formally created in 1936. It contained the municipalities of Abrantes, Alcanena, Almeirim, Alpiarça, Azambuja, Benavente, Cartaxo, Chamusca, Constância, Coruche, Entroncamento, Ferreira do Zêzere, Golegã, Rio Maior, Salvaterra de Magos, Santarém, Sardoal, Tomar, Torres Novas, Vila Franca de Xira and Vila Nova da Barquinha. The largest towns were Santarém and Tomar.
