While Louis was staying in Spain, the
Duchy of Parma had been occupied by French troops in 1796.
Napoleon Bonaparte, who had conquered most of Italy and wanted to gain Spain as an ally against Britain, proposed to compensate the
House of Bourbon for their loss of the Duchy of Parma with the
Kingdom of Etruria, a new state that he created from the
Grand Duchy of Tuscany. This was agreed upon in the
Treaty of Aranjuez. Louis had to receive his investiture from Napoleon in Paris, before taking possession of Etruria. Louis, his wife and his son travelled incognito through France under the name of the Count of Livorno. Having been invested in Paris as King of Etruria, Louis and his family arrived in August 1801 at his new capital, Florence. In 1802, both Louis and his pregnant wife travelled to Spain to attend the double-wedding of Maria Luisa's brother
Fernando and her youngest sister
Maria Isabel. Offshore at Barcelona, Maria Luisa gave birth to their daughter, Marie Louise Charlotte. The couple returned in December of that year, after having been notified of the death of Louis's father. Back in Etruria, Louis's health worsened, and in May 1803, he died at the age of twenty-nine, possibly due to an epileptic crisis. He was succeeded by his son,
Charles Louis, as King Louis II of Etruria, under the regency of his mother, Maria Luisa. ==Ancestry==
