Signature

A member ofPhanariote nobleYpsilantis family, he was the second son ofPrince Constantine Ypsilantis of Moldavia andElisavet Ypsilanti. He was sent to France where he was educated at a French military school.

He distinguished himself as aRussian officer in the campaign of 1814.^[1]

In 1821 he took part in theWallachian uprising under the leadership of his brother Alexandros, that indirectly benefited the Principalities of Moldavia andWallachia.^[2]

After the failure of the uprising in Wallachia, he went to theMorea (Peloponessus), where theGreek War of Independence had just broken out, as representative of Filiki Etaireia and his brother.

He was one of the most conspicuous of the Phanariote leaders during the early stages of the revolt, though he was much hampered by the local chiefs and by the civilian element headed byAlexandros Mavrokordatos;^[1] as a result the organisation of a regular army was slowed and operations were limited.^[3] He took part in the sieges of Tripolitsa, Nafplion and theBattle of Dervenakia, securing the Greek dominion in Morea.

On 15 January 1822, he was elected president of the legislative assembly. However, due to the failure of his campaign in central Greece, and his failure to obtain a commanding position in thenational convention of Astros, he was compelled to retire in 1823.^[4] After the landing ofIbrahim at Morea, he took part in the defence of Naplion in theBattle of the Lerna Mills.

In 1828, he was appointed in the new established regular army byIoannis Kapodistrias as commander of the troops in eastern Greece. On 25 September 1829, he successfully compelled Aslan Bey to capitulate at the Pass of Petra (Battle of Petra), thus ending the active operations of the war.^[4]

He was known for an affair withManto Mavrogenous, who was a Greek heroine of the Greek War of Independence.

He died due to illness inNafplion on 16 August 1832.
